Penn Bioengineers: Cells Control Their Own Fate by Manipulating Their Environment

by Lauren Salig

In these images, the researchers labeled new proteins white, and antibodies against other proteins in different colors. The co-localization of new proteins and antibodies show how cells can impact their local environments.

As different as muscle, blood, brain and skin cells are from one another, they all share the same DNA. Stem cells’ transformation into these specialized cells — a process called cell fate determination — is controlled through various signals from their surroundings.

A recent Penn Engineering study suggests that cells may have more control over their fate than previously thought.

Jason Burdick, Robert D. Bent Professor of Bioengineering, and Claudia Loebel, a postdoctoral researcher in his lab, led the study. Robert Mauck, Mary Black Ralston Professor for Education and Research in Orthopaedic Surgery at Penn’s Perelman School of Medicine, also contributed to the research.

Their study was published in Nature Materials.

A New Microscopy Technique Could Reduce the Risk of LASIK Surgery

Though over ten million Americans have undergone LASIK vision corrective surgery since the option became available about 20 years ago, the procedure still poses some risk to patients. In addition to the usual risks of any surgery however, LASIK has even more due to the lack of a precise way to measure the refractive properties of the eye, which forces surgeons to make approximations in their measurements during the procedure. In an effort to eliminate this risk, a University of Maryland team of researchers in the Optics Biotech Laboratory led by Giuliano Scarcelli, Ph. D., designed a microscopy technique that would allow for precise measurements of these properties.

Using a form of light-scattering technology called Brillouin spectroscopy, Scarcelli and his lab found a way to directly determine a patient’s refractive index – the quantity surgeons need to know to be able to measure and adjust the way light travels through the eye. Often used as a way to sense mechanical properties of tissues and cells, this technology holds promise for taking three-dimensional spatial observations of these structures around the eye. Scarcelli hopes to keep improving the resolution of the new technique, to further understanding of the eye, and reduce even more of the risks involved with LASIK surgery.

Taking Tissue Models to the Final Frontier

Space flight is likely to cause deleterious changes to the composition of bacterial flora, leading to an increased risk of infection. The environment may also affect the susceptibility of microorganisms within the spacecraft to antibiotics, key components of flown medical kits, and may modify the virulence of bacteria and other microorganisms that contaminate the fabric of the International Space Station and other flight platforms.

“It has been known since the early days of human space flight that astronauts are more prone to infection,” says Dongeun (Dan) Huh, Wilf Family Term Assistant Professor in Bioengineering at Penn Engineering. “Infections can potentially be a serious threat to astronauts, but we don’t have a good fundamental understanding of how the microgravity environment changes the way our immune system reacts to pathogens.”

In collaboration with G. Scott Worthen, a physician-scientist in neonatology at the Children’s Hospital of Philadelphia, Huh will attempt to answer this question by sending tissues-on-chips to space. Last June, the Center for the Advancement of Science in Space (CASIS) and the National Center for Advancing Translational Sciences (NCATS), part of the National Institutes of Health (NIH), announced that the duo had received funding to study lung host defense in microgravity at the International Space Station.

Huh and Worthen aim to model respiratory infection, which accounts for more than 30 percent of all infections reported in astronauts. The project’s goals are to test engineered systems that model the airway and bone marrow, a critical organ in the immune system responsible for generating white blood cells, and to combine the models to emulate and understand the integrated immune responses of the human respiratory system in microgravity.

Sappi Limited Teams Up with the University of Maine to Develop Paper Microfluidics

At the Westbrook Technology Center of Sappi, a global pulp and paper company, researchers found ways to apply innovations in paper texture for medical use. So far, these include endeavors in medical test devices and patches for patient diagnostics. In collaboration with the Caitlin Howell, Ph.D., Assistant Professor of Chemical and Biomedical Engineering at the University of Maine, Sappi hopes to continue advances in these unconventional uses of their paper, especially as the business in paper for publishing purposes declines.

Sappi’s projects with the university focus on the development of paper microfluidics devices as what’s now becoming a widespread solution for obstacles in point-of-care diagnostics. One project in particular, called Sharklet, uses a paper that mimics shark skin as a way to impede unwanted microbial growth on the device – a key characteristic needed for its transition into commercial use. Beyond this example, Sappi’s work in developing paper microfluidics underscores the benefits of these devices in their mass producibility and adaptability.

New Observations of the WNT Pathway Deepen the Understanding of Protein Signaling in Cellular Development

Scientists at Rice University recently found that a protein signaling pathway called WNT, typically associated with its role in early organism development, can both listen for signals from a large amount of triggers and influence cell types throughout embryonic development. These new findings, published in PNAS, add to the already known functions of WNT, deepening our understanding of it and opening the doors to new potential applications of it in stem cell research.

Led by Aryeh Warmflash, Ph. D., researchers discovered that the WNT pathway is different between stem cells and differentiated cells, contrary to prior belief that it was the same for both. Using CRISPR-Cas9 gene editing technology, the Warmflash lab observed that the WNT signaling pathway is actually context-dependent throughout the process of cellular development. This research brings a whole new understanding to the way the WNT pathway operates, and could open the doors to new forms of gene therapy and treatments for diseases like cancers that involve genetic pathway mutations.

Synthetic Spinal Discs from a Penn Research Team Might Be the Solution to Chronic Back Pain

Spinal discs, the concentric circles of collagen fiber found between each vertebra of the spine, can be the source of immense back pain when ruptured. Especially for truck and bus drivers, veterans, and cigarette smokers, there is an increased risk in spinal disc rupture due to overuse or deterioration over time. But these patients aren’t alone. In fact, spinal discs erode over time for almost everyone, and are one of the sources of back pain in older patients, especially when the discs erode so much that they allow direct bone-to-bone contact between two or more vertebrae.

Robert Mauck, Ph.D.

Robert Mauck, Ph.D., who is the director of the McKay Orthopaedic Research Laboratory here at Penn and a member of the Bioengineering Graduate Group Faculty, led a research team in creating artificial spinal discs, with an outer layer made from biodegradable polymer and an inner layer made with a sugar-like gel. Their findings appear in Science Translational Medicine. These synthetic discs are also seeded with stem cells that produce collagen over time, meant to replace the polymer as it degrades in vivo over time. Though Mauck and his time are still far from human clinical trials for the discs, they’ve shown some success in goat models so far. If successful, these biodegradable discs could lead to a solution for back pain that integrates itself into the human body over time, potentially eliminating the need of multiple invasive procedures that current solutions require. Mauck’s work was recently featured in Philly.com.

An Untethered, Light-Activated Electrode for Innovations in Neurostimulation

Neurostimulation, a process by which nervous system activity can be purposefully modulated, is a common treatment for patients with some form of paralysis or neurological disorders like Parkinson’s disease. This procedure is typically invasive, and because of the brain’s extreme sensitivity, even the slightest involuntary movement of the cables, electrodes, and other components involved can lead to further brain damage through inflammation and scarring. In an effort to solve this common problem, researchers from the B.I.O.N.I.C. Lab run by Takashi D.Y. Kozai, Ph. D., at the University of Pittsburgh replaced long cables with long wavelength light and a formerly tethered electrode with a smaller, untethered one.

The research team, which includes Pitt senior bioengineering and computer engineering student Kaylene Stocking, centered the device on the principle of the photoelectric effect – a concept first described in a publication by Einstein as the local change in electric potential for an object when hit with a photon. Their design, which includes a 7-8 micron diameter carbon fiber implant, is now patent pending, and Kozai hopes that it will lead to safer and more precise advancements in neurostimulation for patients in the future.

A New Microfluidic Chip Can Detect Cancer in a Drop of Blood

Many forms of cancer cannot be detected until the disease has progressed past the point of optimum treatment time, increasing the risk for patients who receive late diagnoses of these kinds of cancer. But what if the diagnostic process could be simplified and made more efficient so that even a single drop of blood could be enough input to detect the presence of cancer in a patient? Yong Zeng, Ph.D., and his team of researchers at the University of Kansas in Lawrence sought to answer that question.

They designed a self-assembled 3D-nanopatterned microfluidic chip to increase typical microfluidic chip sensitivity so that it can now detect lower levels of tumor-associated exosomes in patient blood plasma. This is in large part due to the nanopatterns in the structure of the chip, which promote mass transfer and increase surface area, which in turn promotes surface-particle interactions in the device. The team applied the device to their studies of ovarian cancer, one of the notoriously more difficult kinds of cancer to detect early on in patients.

A Wearable Respiration Monitor Made from Shrinky Dinks

Michelle Khine, Ph. D., a professor of biomedical engineering at the University of California, Irvine incorporates Shrinky Dinks into her research. After using them once before in a medical device involving microfluidics, her lab recently worked to incorporate them into a wearable respiration monitor – a device that would be useful for patients with asthma, cystic fibrosis, and other chronic pulmonary diseases. The device has the capability to track the rate and volume of its user’s respiration based on measurements of the strain at the locations where the device makes contact with the user’s abdomen.

Paired with Bluetooth technology, this sensor can feed live readings to a smartphone app, giving constant updates to users and doctors, as opposed to the typical pulmonary function test, which only provides information from the time at which the test takes a reading. Though Khine and her team have only tested the device on healthy patients so far, they look forward to testing with patients who have pulmonary disorders, in hopes that the device will provide more comprehensive and accessible data on their respiration.

Refining Autism Treatments Using Big Data

Though treatments like therapy and medication exist for patients with autism, one of the biggest challenges that those caring for these patients face is in measuring their effects over time. Many of the markers of progress are qualitative, and based on a given professional’s opinion on a case-by-case basis. But now, a team of researchers from Rensselaer Polytechnic Institute (RPI) hopes to change that with the use of big data.

Juergen Hahn, Ph. D., and his lab recently published a paper in Frontiers in Cellular Neuroscience discussing their findings in connecting metabolic changes with behavioral improvements in autistic patients. Their analysis looks for multiple chemical and medical markers simultaneously in data from three distinct clinical trials involving metabolic treatment for patients. Being able to quantitatively describe the effects of current autism treatments would revolutionize clinical trials in the field, and lead to overall better patient care.

Penn Engineers Can Detect Ultra Rare Proteins in Blood Using a Cellphone Camera

One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many conditions, such as the early detection of certain cancers or the diagnosis of traumatic brain injury, where the relevant biomarkers only appear in vanishingly small quantities. Commercial approaches to ultrasensitive protein detection are starting to become available, but they are based on expensive optics and fluid handlers, which make them relatively bulky and expensive and constrain their use to laboratory settings.

Knowing that having this sort of diagnostic system available as a point-of-care device would be critical for many conditions — especially traumatic brain injury — a team of engineers led by Assistant Professor in the Department of Bioengineering, David Issadore, Ph.D., at the University of Pennsylvania have developed a test that uses off-the-shelf components and can detect single proteins with results in a matter of minutes, compared to the traditional workflow, which can take days.

Treating Cerebral Palsy with Battery-Powered Exoskeletons

Cerebral palsy is one of the most common movement disorders in the United States. The disorder affects a patient’s control over even basic movements like walking, so treatments for cerebral palsy often involve the use of assistive devices in an effort to give patients better command over their muscles. Zach Lerner, Ph.D., is an Assistant Professor of Mechanical Engineering and faculty in Northern Arizona University’s Center for Bioengineering Innovation whose research looks to improve these kinds of assistive devices through the use of battery-powered exoskeletons.

Lerner and his lab recently received three grants, one each from the National Institute of Health (NIH), the National Science Foundation (NSF), and the Arabidopsis Biological Resource Center, to continue their research in developing these exoskeletons. Their goal is to create devices with powered assistance at joints like the ankle or knee to help improve patient gait patterns in rehabilitating the neuromuscular systems associated with walking. The team hopes that their work under these new grants will help further advance treatment for children with cerebral palsy, and improve overall patient care.

Detecting Infectious Diseases with Paper-Based Devices

Despite great advancements in diagnostics technology over the past few decades, patient accessibility to these technologies remains one of the biggest challenges of the field today. Particularly in low-resource areas, even simple processes can end up taking weeks or months to return results from tests that are normally completed in days. But what if these tests could be simplified to smaller, at-home tests based on properties of microfluidics – something like a pregnancy test but for infectious diseases like HIV?

Jacqueline Linnes, Ph.D., and her team of researchers at Purdue University are working towards finding a way to do just that by creating paper-based devices that use microfluidics to help carry out the necessary diagnostic tests. Specifically, her lab designed such a paper-based system that can detect HIV nucleic acids within 90 minutes of receiving a drop of patient blood. The success of this design shows promise for producing devices for diseases whose diagnostics process involve similar pathways of pathogen detection, opening the door to more applications of at-home tests based in the properties of paper microfluidics.

Here at Penn, undergraduate bioengineering students enrolled in the two-semester laboratory course Bioengineering Modeling, Analysis, and Design (BE 309 & BE 310) have the chance to create their own models of paper microfluidics delivery systems based on given time constraints in a multi-step process. Though the students’ challenge only involves water as a substrate, Linnes’ research demonstrates the later implications of studying fluid flow through a medium as cheap and accessible as paper.

Funding for Cancer Research in Tumor Mimicry and Imaging

Two of the deadliest forms of cancer today are breast cancer and pancreatic cancer, with the latter having a five-year survival rate of only about 8%. Because cancer treatments are often adjusted according to a unique patient-to-patient basis, learning how to improve predictions of tumor behavior could help determine proper therapies sooner.

Chien-Chi Lin, Ph.D., an associate professor of biomedical engineering at Indiana University – Purdue University Indianapolis, recently received a grant from the National Institute of Health to advance his research in pancreatic cancer treatment. His project under the grant involves the development of bio-inspired, responsive, and viscoelastic (BRAVE) cell-laden hydrogels to help understand cell interactions in pancreatic ductal adenocarcinoma, which is the most common form of malignancy in the pancreas. These hydrogels mimic tumor tissue, as well as model tumor development over time, helping to eventually find better ways of treating pancreatic cancer.

In other news surrounding cancer-related research, a team of researchers led by Kenneth Tichauer, Ph.D., at the Illinois Institute of Technology won the university’s Nayar Prize for their development of the Agent-Dependent Early Photon Tomography (ADEPT) Cancer Imager, a machine designed to find early tumor development in the lymph nodes of breast cancer patients. Through the use of a special dyeing process that now dyes the entire lymph node, providing a sharper image that allows for a quicker discovery of smaller tumors.

Bioengineers Tackle Heart Disease

Heart disease is currently the leading cause of death in the United States, resulting in about 630,000 deaths every year according to the Center for Disease Control. One of the most common side effects of heart disease is damage to blood vessels and cardiac tissue, which can ultimately lead to conditions like high blood pressure, arrhythmia, and even cardiac arrest. In serious cases of irreversible heart damage, often the only option for patients is a full heart transplant, and efforts to engineer vascularized cardiac tissue grafts have proved challenging in research so far.

But researchers Ying Zheng, Ph.D., and Charles Murry, M.D., Ph.D., both of whom have joint appointments in Bioengineering at the University of Washington, have found success in using human microvascular grafts to create working blood vessels in vitro to treat infarcted rat hearts. The new heart muscle, developed from human embryonic stem cell-derived endothelial cells in petri dishes, was grown with a focus on not only being able to easily integrate it in vivo, but also in creating a patch of vasculature that closely mirrored that of the heart. In concentrating more on the mechanical aspects of the blood vessel network, Zheng and Murry were able to better restore normal blood flow to the damaged rat hearts after integration of the grafts. The study appears in a recent edition of Nature Communications.

Another team of bioengineers, led by Michael Sacks, Ph.D. at the University of Texas at Austin, recently invented a software-based method for repairing mitral valves in the heart. Their work, published in the International Journal for Numerical Methods in Biomedical Engineering, uses computational modeling techniques to create a noninvasive way of simulating repairs to the mitral valve, which will allow for a better prediction of surgical procedures and postoperative side effects on a more patient-specific basis. This ability to know which treatment plan may be best-suited for a given patient is important especially for valve repair, as heart valves are notoriously difficult to model or image due to the complexity of their functions. But through the use of advanced technology in 3D echocardiography, Sacks and his team say that their new model is accurate enough to rely on in clinical settings.

Virtual Reality Assists in the Evaluation of Surgery

Any form of surgery is always a high risk procedure, as it is subject to a wide variety of sources of human error and irregularity, even with the best surgeons. Certainly, there should be a system in place to not only continually assess the knowledge of surgeons throughout their careers, but also to evaluate their practices and techniques during operation. Such an evaluation, however, would put patients at risk during the assessment of the surgeon.

But now a team of researchers from Rensselaer Polytechnic Institute has developed a way of simulating colorectal surgical procedures using virtual reality technology. Suvranu De, Sc.D. — the J. Erik Jonsson ‘22 Distinguished Professor of Engineering and Head of the Department of Mechanical, Aerospace and Nuclear Engineering with joint appointments in Biomedical Engineering and Information Technology and Web Science —leads the project which incorporates both visual and tactile feedback for users to employ as a tool for both training and evaluating colorectal surgeons. While virtual reality simulators have been used for similar applications related to procedures like the colonoscopy, they have yet to be fully developed for open surgical procedures, because of the difficulties in creating a fully engaged and immersive environment. Nonetheless, De and his team hope that their work will lead to the creation of the first “Virtual Intelligent Preceptor,” which will allow for more advanced technological innovations in aspects of surgical education that have so far been difficult to standardize. Support for the project comes from the National Institute of Biomedical Imaging and Bioengineering (NBIB).

Microscopic Magnets Reduce Pain

A new approach uses “mechanoceuticals” to treat pain.

Drugs are commonly injected directly into an injury site to speed healing. For chronic pain, clinicians can inject drugs to reduce inflammation in painful joints, or can inject nerve blockers to block the nerve signals that cause pain. In a recent study, a group from UCLA developed a technique to deform a material surrounding nerve fibers to trigger a response in the fibers that would relieve pain. The combination of mechanics and treatment – i.e., ‘mechanoceuticals’ – is a clever way to trick fibers and reverse painful symptoms. Done without any injections and simply controlling magnetic fields outside the body, this approach can be reused as necessary.

The design of this mechanoceutical was completed by Dino Di Carlo, PhD, Professor of Bioengineering, and his team at UCLA’s Sameuli School of Engineering. By encasing tiny, magnetic nanoparticles within a biocompatible hydrogel, the group used magnetic force to stimulate nerve fibers and cause a corresponding decrease in pain signals. This promising development opens up a new approach to pain management, one which can be created with different biomaterials to suit different conditions, and delivered “on demand” without worrying about injections or, for that matter, any prescription drugs.

Understanding the Adolescent Brain

It’s no surprise that adults and adolescents often struggle to understand one another, but the work of neurologists and other researchers provides a possible physical reason for why that might be. Magnetic resonance elastrography (MRE) is a tool used in biomedical imaging to estimate the mechanical properties, or stiffness, of tissue throughout the body. Unexpectedly, a recent study suggests that brain stiffness correlates with cognitive ability, suggesting MRE may provide insight into patients’ behavior, psychology, and psychiatric state.

A new paper in Developmental Cognitive Neuroscience published the results of a study using MRE to track the relative “stiffness” vs. “softness” of adult and adolescent brains. The University of Delaware team, led by Biomedical Engineering Assistant Professor Curtis Johnson, PhD, and his doctoral student Grace McIlvain, sampled 40 living subjects (aged 12-14) and compared the properties to healthy adult brains.

The study found that children and adolescent brains are softer than those of adults, correlating to the overall malleability of childhood development. The team hopes to continue their studies with younger and older children, looking to demonstrate exactly when and how the change from softness to stiffness takes place, and how these properties correspond to individual qualities such as risk-taking or the onset of puberty. Eventually, establishing a larger database of measurements in the pediatric brain will help further studies into neurological and cognitive disorders in children, helping to understand conditions such as multiple sclerosis, autism, and cerebral palsy.

Can Nanoparticles Replace Stents?

Researchers and clinicians have made amazing advances in heart surgery. Stents, in particular, have become quite sophisticated: they are used to both prop open clogged arteries as well as deliver blood-thinning medication slowly over days to weeks in the area of the stent. However, the risk of blood clotting increases with stents and the blood vessels can constrict over time after the stent is placed in the vessel.

A recent NIH grant will support the design of a stent-free solution to unclog blood vessels. Led by Shaoqin Gong, PhD, Vilas Distinguished Professor of Biomedical Engineering at UW-Madison, the team used nanoparticles (or nanoclusters) to directly target the affected blood vessels and prevent regrowth of the cells post-surgery, eliminating the need for a stent to keep the pathways open. These nanoclusters are injected through an intravenous line, further reducing the risks introduced by the presence of the stent. As heart disease affects millions of people worldwide, this new material has far-reaching consequences. Their study is published in the September edition of Biomaterials.

NIST Grant Supports

The National Institute of Standards and Technology (NIST) awarded a $30 million grant to Johns Hopkins University, Binghamton University, and Morgan State University as part of their Professional Research Experience Program (PREP).

Converting Fat to Fight Obesity

White fat stories calories and provides the body with insulation.

There are two types of fat in the human body: brown and white. Brown fat, the “good” fat, is rich in mitochondria, which gives it its brown appearance. Whereas white fat stores calories and acts as an insulator, mitochondria-rich brown fat burns energy to produce heat throughout the body and maintains body temperature. White fat, conversely, uses its stored energy to insulate the body and keep its temperature level. While all fat serves a purpose in the body, an excess of white fat cells causes obesity, a condition affecting one in three adults in the U.S. and the root cause of many potential health problems. Finding ways to convert white fat to brown opens a possibility of treating this problem naturally.

A new study in Scientific Reports proposes a clever way to convert fat types. Professor of Biomedical Engineering Samuel Sia, PhD, of the Columbia University School of Engineering and Applied Science, led a team which developed a method of converting white fat into brown using a tissue-grafting technique. After extracting and converting the fat, it can then be transplanted back into the patient. White fat is hard-wired to convert to brown under certain conditions, such as exposure to cold temperatures, so the trick for Dr. Sia’s team was finding a way to make the conversion last for long periods. The studies conducted with mice suggested that using these methods, newly-converted fat stayed brown for a period of two months.

Dr. Sia’s team will proceed to conduct further tests, especially on the subjects’ metabolism and overall weight after undergoing the procedure, and they hope that eventual clinical trials will result in new methods to treat or even prevent obesity in humans.

Cremins Lab Student Appointed Blavatnik Fellow

Linda Zhou is currently pursuing her MD/PhD in Genomics and Computational Biology under the supervision of Dr. Jennifer Phillips-Cremins.

The Perelman School of Medicine named Linda Zhou, a student in BE’s Cremins Laboratory, a Blavatnik Fellow for the 2018-2019 academic year. The selection process for this award is highly competitive, and Linda’s selection speaks to the excellent quality of her scholarship and academic performance. The fellows will be honored in a special ceremony at the Museum of Natural History in New York City.

Linda received her B.S. in Biophysics and Biochemistry from Yale University and is currently pursuing her M.D./Ph.D. in the Genomics and Computational Biology Program at Penn. “I am honored to be named a Blavatnik Fellow and am extremely excited to continue my graduate studies investigating neurological disorders and the 3D genome,” she said. “This support will be integral to achieving my long term goal of driving scientific discovery that will help treat human disease.”

Linda’s research is overseen by Penn Bioengineering Assistant Professor Jennifer Phillips-Cremins, PhD. “Linda is an outstanding graduate student,” said Dr. Cremins. “It is a true delight to work with her. She is hard working, intelligent, kind, and has extraordinary leadership ability. Her unrelenting search for ground-state truth makes her a shining star.”

The Blavatnik Family Fellowship in Biomedical Research is a new award announced by the Perelman School of Medicine in May of this year. This generous gift from the Blavatnik Family Foundation awards $2 million to six recipients in the Biomedical Graduate Studies Program at Penn for each of the next four years.

Growing Lungs in a Lab

As the demand for lung transplants continues to rise, so does the need for safe and effective transplanted lungs. Bioengineered lungs grown or created in labs are one way of meeting this demand. The problem – as is ever the case with transplants – is the high rate of rejection. The results of success are always better when cells from the patient herself (or autologous cells) are used in the transplanted organ.

Recently Joan Nichols, PhD, Professor of Internal Medicine, and Microbiology and Immunology, at the University of Texas Medical Branch at Galveston, successfully bioengineered the first human lung. Her latest study published in Science Translational Medicine describes the next milestone for Dr. Nichols’ lab: successfully transplanting a bioengineered lung into a pig.

These advances are possible due to Dr. Nichols’ work with autologous cells, continuing the trend of “on demand” medicine (i.e. medicine tailor for a specific patient) which we track on this blog. Dr. Nichols’ particular method is to build the structure of a lung (using the harvested organs of dead pigs in this case), de-cellularize the tissue, and then repopulate it with autologous cells from the intended recipient. This way, the host body recognizes the cells as friendly and the likelihood of acceptance increases. While further study is needed before clinical trials can begin, Dr. Nichols and her team see the results as extremely promising and believe that we are on the way to bioengineered human lungs.

Nanoparticles Combat Dental Plaque

Combine a diet high in sugar with poor oral hygiene habits and dental cavities likely result. The sugar triggers the formation of an acidic biofilm (plaque) on the teeth, eroding the surface. Early childhood dental cavities affect one in every four children in the United States and hundreds of millions more globally. It’s a particularly severe problem in underprivileged populations.

In a study published in Nature Communications this week, researchers led by Hyun (Michel) Koo of the University of Pennsylvania School of Dental Medicine in collaboration with David Cormode of Penn’s Perelman School of Medicine and School of Engineering and Applied Science used FDA-approved nanoparticles to effectively disrupt biofilms and prevent tooth decay in both an experimental human-plaque-like biofilm and in an animal model that mimics early-childhood caries.

Dr. David Cormode is Assistant Professor of Radiology and Secondary Faculty in Bioengineering at Penn. His research includes Bioengineering Therapeutics, Devices and Drug Delivery and Biomaterials.

Stopping the Flu from Catching On

The flu virus is notoriously contagious, but there may be a way to stop it before it starts. In order for the influenza virus to successfully transport itself into the cells of a human host, it needs a certain protein called hemagglutinin which mediates its entry. By interfering with this vital ingredient, researchers can effectively kill the virus.

A new study in the Proceedings of the National Academy of Sciences discusses a method of disrupting the process by which this protein causes the virus to infect its host cells. This discovery could lead to more effective flu vaccines that target the flu virus at its root, rather than current ones which have to keep up with the ongoing changes and mutations of the virus itself. Indeed, the need for different vaccines to address various “strains” of the flu is moot if a vaccine can stop the virus from infecting people in the first place.

This breakthrough results from grants provided by the NSF, the Welch Foundation, and the NIH to Rice University and Baylor College of Medicine. Lead researchers José Onuchic, PhD, Harry C. and Olga K. Wiess Chair of Physics and Professor of Chemistry and BioSciences at Rice University; Jianpeng Ma, PhD, Professor of Bioengineering at Rice University and Lodwick T. Bolin Professor of Biochemistry at Baylor College of Medicine; and Qinghua Wang, PhD, Assistant Professor of Biochemistry at Baylor College of Medicine. Their team will continue to study the important role proteins play in how the flu virus operates.

People and Places

This week, we congratulate a few new leadership appointments in bioengineering. First, the Georgia Institute of Technology appointed Penn BE alumnus Andréas García, PhD, the new Executive Director of the Parker H. Petit Institute for Bioengineering and Bioscience. In addition to his new role, Dr. García is also the George W. Woodruff School of Mechanical Engineering Regents Professor. He conducts research in biomolecular, cellular, and tissue engineering and collaborates with a number of research centers across Georgia Tech. Dr. García graduated with both his M.S.E. and Ph.D. from the University of Pennsylvania’s Department of Bioengineering.

Secondly, the University of Minnesota Institute for Engineering in Medicine (IEM) named the Distinguished McKnight University Professor John Bischof, PhD, their new director. This follows Dr. Bischof’s recent position as interim director for the IEM. Dr. Bischof earned his Ph.D. in Mechanical Engineering at the University of California at Berkeley, and is currently a faculty member in both the Mechanical Engineering and Biomedical Engineering Departments at the University of Minnesota. Dr. Bischof holds the Carl and Janet Kuhrmeyer Chair in Mechanical Engineering.

At an earlier, but no less impressive, point in his academic career, Tanishq Abraham became the youngest person to graduate with a degree in biomedical engineering. The fifteen year old recently graduated summa cum laude from the University of California, Davis. As part of his graduating research, Abraham – a first-generation Indian-American – designed a device to measure the heart rates of burn victims. Abraham has already been accepted by U.C. Davis for his Ph.D. and plans to continue on to his M.D.

Finally, the work continues to create affordable and well-fitted prosthetics, especially for remote, rural, and underfunded areas both in the U.S. and abroad. Unfortunately, recent studies published by the Centre for Biomedical Engineering at the India Institute of Technology Delhi (IIT) demonstrate the uphill nature of this battle; stating that India alone contains over half a million upper limb amputees. To address this explosive population, researchers and entrepreneurs are using new bioengineering technologies such as digital manufacturing, 3D scanning and printing, and more. The best innovations are those that save time, resources, and money, without sacrificing quality in the prosthetic or patient comfort. Penn Engineering’s Global Biomedical Service (GBS) program similarly responds to this need, as each year students follow an academically rigorous course with a two-week immersive trip to China, where they learn how to create and fit prosthetic limbs for local children in conjunction with Hong Kong Polytechnic University.

New Data Analysis Methods

Like many other fields, biomedical research is experiencing a data explosion. Some estimates suggest that the amount of data generated from the health sciences is now doubling every eighteen months, and experts expect it to double every seventy-three days by 2020.  One challenge that researchers face is how to meaningfully analyze this data tsunami.

The challenge of interpreting data occurs at all scales, and a recent collaboration shows how new approaches can allow us to handle the volumes of data emerging at the level of individual cells to infer more about how biology “works” at this level.  Wharton Statistics Department researchers Mo Huang and Jingshu Wang (PhD Student and Postdoctoral Researcher, respectively) collaborated with Arjun Raj’s lab in Bioengineering and published their findings in recent issues of Nature Methods and Proceedings of the National Academy of Sciences.  One study focused on a de-noising technique called SAVER to provide more precise data from single cell experiments and significantly improves the ability to detect trends in a dataset, similar to how increasing sample size helps improve the ability to determine differences between experimental groups.  The second method, termed DESCEND, creates more accurate characterization of gene expression that occur in individual cells. Together these two methods will improve data collection for biologists and medical professionals working  to diagnose, monitor, and treat diseased cells.

Dr. Raj’s team contributed data to the cause and acted as consultants on the biological aspects of this research. Further collaboration involved Mingyao Li, PhD, Professor of Biostatistics at the Perelman School of Medicine, and Nancy Zhang, PD, Professor Statistics at the Wharton School. “We are so happy to have had the chance to work with Nancy and Mingyao on analyzing single cell data,” said Dr. Raj. “The things they were able to do with our data are pretty amazing and important for the field.”

Advancements in Biomaterials

This blog features many new biomaterials techniques and substances, and there are several exciting new developments to report this week. First, the journal of Nature Biomedical Engineering published a study announcing a new therapy to treat or even eliminate lung infections, such as those acquired while in hospital or as the result of cystic fibrosis, which are highly common and dangerous. Researchers identified and designed viruses to target and kill the bacteria which causes these infections, but the difficulty of administering them to patients has proven prohibitive. This new therapy, developed by researchers at the Georgia Institute of Technology, is administered as a dry powder directly to the lungs and bypasses many of the delivery problems appearing in past treatments. Further research on the safety of this method is required before clinical trials can begin.

A team at Harvard University published another recent study in Nature Biomedical Engineering announcing their creation of a tissue-engineered scale model of the left human heart ventricle. This model is made from degradable fibers that simulate the natural fibers of heart tissue. Lead investigator Professor Kevin Kit Parker, PhD, and his team eventually hope to build specific models culled from patient stem cells to replicate the features of that patient’s heart, complete with the patient’s unique DNA and any heart defects or diseases. This replica would allow researchers and clinicians to study and test various treatments before applying them to a specific patient.

Lastly, researchers at the Tufts University School of Engineering published in the Proceedings of the National Academy of Sciences on their creation of flexible magnetic composites that respond to light. This material is capable of macroscale motion and is extremely flexible, allowing its adaptation into a variety of substances such as sponges, film, and hydrogels. Author and graduate student Meg Li explained that this material differs from similar substances in its complexity; for example, in the ability for engineers to dictate specific movements, such as toward or away from the light source. Co-author Fiorenzo Omenetto, PhD, suggests that with further research, these movements could be controlled at even more specific and detailed levels.

CFPS: Getting Closer to “On Demand” Medicine

A recent and growing trend in medicine is the move towards personalized or “on demand” medicine, allowing for treatment customized to specific patients’ needs and situations. One leading method is Cell-Free Protein Synthesis (CFPS), a way of engineering cellular biology without using actual cells. CFPS is used to make substances such as medicine, vaccines, and chemicals in a sustainable and portable way. One instance if the rapid manufacture of insulin to treat diabetic patients. Given that many clinics most in need of such substances are found in remote and under-served locations far away from well-equipped hospitals and urban infrastructure, the ability to safely and quickly create and transport these vital substances to patients is vitally important.

The biggest limiting factor to CFPS is difficulty of replicating Glycosylation, a complex modification that most proteins undergo. Glycosylation is important for proteins to exert their biological function, and is very difficult to synthetically duplicate. Previously, achieving successful Glycosylation was a key barrier in CFPS. Fortunately, Matthew DeLisa, PhD, the Williams L. Lewis Professor of Engineering at Cornell University and Michael Jewett, PD, Associate Professor of Chemical and Biological Engineering at Northwestern University, have created a “single-pot” glycoprotein biosynthesis that allows them to make these critical molecules very quickly. The full study was recently published in Nature Communications. With this new method, medicine is one step closer to being fully “on demand.”
