Penn Engineers: Cells Require Gene Expression Feedback to Keep Moving

By Lauren Salig

When cells move throughout the body, they do so by dragging themselves, using molecular “arms” to pull themselves closer to where they need to be while unlatching themselves from the area they’re moving away from. In a recent study, Penn Engineers looked at a few mechanobiological factors that help regulate cells’ migration towards their destination, providing new insight into the gene expression feedback loops that keep them from getting stuck.

Joel Boerckel and Devon Mason

The research was led by Joel Boerckel, Assistant Professor of Orthopaedic Surgery in the Perelman School of Medicine and in Bioengineering in Penn Engineering, and bioengineering graduate student Devon Mason. Co-authors include bioengineering graduate student Joseph Collins and researchers from the University of Notre Dame, Indiana University and Purdue University.

The study was published in the Journal of Cell Biology.

BE’s Danielle Bassett Profiled in Science Magazine

Danielle Bassett, PhD

Danielle Bassett, Eduardo D. Glandt Faculty Fellow and Associate Professor in theDepartment of Bioengineering, grew up in central Pennsylvania where she and her 10 siblings were homeschooled. Back then, Bassett had aspirations to become a professional pianist, a dream shattered by stress fractures in her arm at age 16.

Now, Bassett is a renowned physicist and MacArthur fellow who has pushed the field of network science, which studies connections and interactions between parts of a whole, to new realms. Bassett’s research focuses on brain function, including work on how brains of people with schizophrenia are organized, how brain communication changes with learning, and how the brain is able to switch between tasks.

Kelly Servick of Science sat down with Bassett to talk through her incredible journey from child pianist to leading network scientist:

““By 17, discouraged by her parents from attending college and disheartened at her loss of skill while away from the keys, she expected that responsibilities as a housewife and mother would soon eclipse any hopes of a career. ‘I wasn’t happy with that plan,’ she says.

Instead, Bassett catapulted herself into a life of research in a largely uncharted scientific field now known as network neuroscience. A Ph.D. physicist and a MacArthur fellow by age 32, she has pioneered the use of concepts from physics and math to describe the dynamic connections in the human brain. ‘She’s now the doyenne of network science,’ says theoretical neuroscientist Karl Friston of University College London. ‘She came from a formal physics background but was … confronted with some of the deepest questions in neuroscience.’”

New Vascularized Patches Could Help Patient Recovery from Heart Attacks

Heart attacks are the result of a stoppage of blood flow to the heart – an interruption to normal function that can result in severe tissue damage, or even tissue death. This loss of healthy tissue function is one of the biggest challenges in treating patients that undergo heart attacks, as the damaged tissue increases their risk of having future attacks. One of the main solutions to this issue right now is the creation of cardiac tissue scaffolds using stem cells to create a platform for new and healthy tissue to grow in vivo. A group of biomedical engineers at Michigan Technological University hopes to expand on this basis by focusing not just on cellular alignment in the scaffold but on that of microvessels too. Led by Feng Zhao, Ph.D., Associate Professor of Biomedical Engineering, the team hopes that this new attention on microvessel organization will improve the vasculature of the scaffolds, and thus improve the success of the scaffolds in vivo, allowing for a better recovery from heart attacks.

Some Stem Cells May Be More Fit Than Others

Stem cells are one of the hottest research areas in the field of bioengineering today. Widely known as the cells in the human embryo that have the ability to eventually transform into specific cells for the brain, lung, and every other organ, stem cells are also of recent interest because researchers found ways to reverse this process, transforming organ-specific cells back to the pluripotent stem cell level. This achievement however, is mostly applicable to individual stem cells, and doesn’t fully encapsulate the way this process might work on a larger population level. So Peter Zandstra, Ph. D., a bioengineering faculty member at the University of British Columbia, decided to research just that.

Using mouse embryonic fibroblasts (MEFs), Zandstra and his lab attempted to track the cells throughout their reprogramming, to more clearly trace each back to its respective parent population. Surprisingly, they found that after only one week of reprogramming, nearly 80% of the original cell population had been removed, meaning that most of the parent generation was not “fit” enough to undergo the process of reprogramming, indicating that perhaps some stem cells will have a better chance of survival in this process than others. This research may suggest that not all cells have the capacity to undergo reprogramming, as many researchers originally thought.

A New Microdevice Will Help Model Bronchial Spasms

The difficulty in breathing associated with asthma is the result of bronchial spasms, which are a kind of muscle contraction in the airways. But little was known about just how these spasms occurred in patients, so Andre Levchenko, Ph.D., Professor of Biomedical Engineering at Johns Hopkins, and his lab created a microdevice to model them. Calling the device a “bronchi on a chip,” Levchenko and his team used a microphysiological model to look at some of the biochemical and mechanical signals associated with these kinds of muscle contractions. They found that the contractions operate in a positive feedback system, so that those caused by disturbance from allergens will subsequently cause even more contractions to occur. But surprisingly, they also found that a second contraction, if triggered at the right time during the initial contraction, could actually stop the process and allow the muscles to relax. Because asthma is a notoriously difficult disease to translate from animal to human models, this new device opens the door to understanding different mechanisms of asthma before taking research to clinical trials.

New CHOP Research Center to Focus Research on Pediatric Airway Disorders

A new bioengineering lab at the Children’s Hospital of Philadelphia called the Center for Pediatric Airway Disorders will specialize in a variety of airway procedures for pediatric patients such as tracheal reconstruction and recurrent laryngeal nerve reinnervation. This new lab will be one of the first to give a unique focus to the application of bioengineering to pediatric laryngology. The interdisciplinary center brings together students and researchers from all different fields, including materials science and microbiology, to find new ways of repairing tissue and regenerating organs related to respiratory disorders. Specific areas of research will involve the modeling of children’s vocal cords, understanding the mechanisms of fibrosis, and improving surgical procedures.

Deeper Understanding of Sickle Cell Anemia Could Lead to New Treatments

Though sickle cell anemia is a common and well-known disease, a new study of its causes at the nanoscale level might reveal previously unknown information about the assembly of hemoglobin fibers. Using microscopes with the ability to visualize these molecules at such a small level, researchers at the University of Minnesota found that the beginning organizations that lead to sickle cell anemia are much less ordered than originally thought. Led by Associate Professor of Biomedical Engineering David Wood, Ph.D., the team of researchers used this higher level of microscopy to find that hemoglobin self-assembly process, which was originally thought to be 96% efficient, is actually only 4% efficient. Wood hopes that this new knowledge will help allow for the development of new and better treatments for patients with sickle cell anemia, as there are currently only two FDA-approved ones on the market.

Throughout the 60-year history of the U.S. space program—from the Mercury capsules of the 1960s to today’s International Space Station—astronauts have been getting sick. Researchers know being in orbit seems to suppress their immune systems, creating a more fertile ground for infections to grow. But nobody really understands why.

Early on the morning of April 26, a SpaceX Falcon 9 rocket will launch a cargo mission to the ISS from Cape Canaveral Air Force Station. Along with fresh water, food, and other necessities for the crew, the craft will be carrying two experiments designed by Penn scientists that could help shed light on why bugs have bedeviled space travelers.

For more than a decade, Dan Huh, the Wilf Family Term Assistant Professor of Bioengineering in the School of Engineering and Applied Science, has been developing super-small devices that use living cells to stand in for larger organs. These organs-on-a-chip hold great promise for all kinds of research, from diagnosing disease to curing them. They’re also a way to test things, including drugs and cosmetics, in a way that mimics real life without relying on animal subjects.

Tulane Researchers Use Cancer Imaging Technique to Help Detect Preeclampsia

Preeclampsia is potentially life-threatening pregnancy disorder that typically occurs in about 200,000 expectant mothers every year. With symptoms of high blood pressure, swelling of the hands and feet, and protein presence in urine, preeclampsia is usually treatable if diagnosed early enough. However, current methods for diagnosis involve invasive procedures like cordocentesis, a procedure which takes a sample of fetal blood.

Researchers at Tulane School of Medicine led by assistant professor of bioengineering Carolyn Bayer, Ph.D., hope to improve diagnostics for preeclampsia with the use of spectral photoacoustic imaging. Using this technique, Bayer’s team noticed a nearly 12 percent decrease in placental oxygenation in rats with induced preeclampsia when compared to normal pregnant rats after only two days. If success in using this imaging technology continues at the clinical level, Bayer plans to find more applications of it in the detection and diagnosis of breast and ovarian cancers as well.

New CRISPR-powered device detects genetic mutations in minutes 

Two groups of researchers from the University of California, Berkeley and the Keck Graduate Institute of the Claremont Colleges recently collaborated to design what they call a “CRISPR-Chip” –  a combination of the CRISPR-Cas9 System with a graphene transistor to sequence DNA for the purpose of genetic mutation diagnosis. While companies like 23andMe made genetic testing and analysis more common and accessible for the general public in recent years, the CRISPR-Chip looks to streamline the technology even more.

This new chip eliminates the long and expensive amplification process involved in the typical polymerase chain reaction (PCR) used to read DNA sequences. In doing so, the CRISPR-Chip is much more of a point-of-care diagnostic, having the ability to quickly detect a given mutation or sequence when given a pure DNA sample. Led by Kiana Aran, Ph.D., the research team behind the CRISPR-Chip hopes that this new combination of nanoelectronics and modern biology will allow for a new world of possibilities in personalized medicine.

New Method of Brain Stimulation Might Alleviate Symptoms of Depression

Depression is one of the most common mental health disorders in the United States, with nearly 3 million cases every year. For most patients suffering from depression, treatment involves prolonged psychotherapy, antidepressant medication, or even electroconvulsive therapy in extreme cases. Now, scientists at the University of North Carolina School of Medicine study the use of transcranial alternating current stimulation (tACS) to alleviate symptoms of depression.

Led by Flavio Frohlich, Ph.D., who has an adjunct appointment in biomedical engineering, this team of researchers based this new solution on information from each patient’s specific alpha oscillations, which are a kind of wave that can be detected by an electroencephalogram (EEG). Those who suffer from depression tend to have imbalanced alpha oscillations, so Frohlich and his team sought to use tACS to restore this balance in those patients. After seeing positive results from data collected two weeks after patients in a clinical trial receives the tACS treatment, Frohlich hopes that future applications will include treatment for even more mental health disorders and psychiatric illnesses.

University of Utah Researchers Receive Grant to Improve Hearing Devices for Deaf Patients

Engineers at the University of Utah are part of team that recently received a $9.7 million grant from the National Institute of Health (NIH) to design new implantable hearing devices for deaf patients, with the hope to improve beyond the sound quality of existing devices. The work will build upon a previous project at the University of Utah called the Utah Electrode Array, a brain-computer interface originally developed by Richard Normann, Ph.D., that can send and receive neural impulses to and from the brain. This new device will differ from a typical cochlear implant because the Utah Electrode Array assembly will be attached directly to the auditory nerve instead of the cochlea, providing the patient with a much higher resolution of sound.

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.
