Penn Anti-Cancer Engineering Center Will Delve Into the Disease’s Physical Fundamentals

by Evan Lerner

A colorized microscope image of an osteosarcoma shows how cellular fibers can transfer physical force between neighboring nuclei, influencing genes. The Penn Anti-Cancer Engineering Center will study such forces, looking for mechanisms that could lead to new treatments or preventative therapies.

Advances in cell and molecular technologies are revolutionizing the treatment of cancer, with faster detection, targeted therapies and, in some cases, the ability to permanently retrain a patient’s own immune system to destroy malignant cells.

However, there are fundamental forces and associated challenges that determine how cancer grows and spreads. The pathological genes that give rise to tumors are regulated in part by a cell’s microenvironment, meaning that the physical push and pull of neighboring cells play a role alongside the chemical signals passed within and between them.

The Penn Anti-Cancer Engineering Center (PACE) will bring diverse research groups from the School of Engineering and Applied Science together with labs in the School of Arts & Sciences and the Perelman School of Medicine to understand these physical forces, leveraging their insights to develop new types of treatments and preventative therapies.

Supported by a series of grants from the NIH’s National Cancer Institute, the PACE Center is Penn’s new hub within the Physical Sciences in Oncology Network. It will draw upon Penn’s ecosystem of related research, including faculty members from the Abramson Cancer Center, Center for Targeted Therapeutics and Translational Nanomedicine, Center for Soft and Living Matter, Institute for Regenerative Medicine, Institute for Immunology and Center for Genome Integrity.

Dennis Discher and Ravi Radhakrishnan

The Center’s founding members are Dennis Discher, Robert D. Bent Professor with appointments in the Departments of Chemical and Biomolecular Engineering (CBE), Bioengineering (BE) and Mechanical Engineering and Applied Mechanics (MEAM), and Ravi Radhakrishnan, Professor and chair of BE with an appointment in CBE.

Discher, an expert in mechanobiology and in delivery of cells and nanoparticles to solid tumors, and Radhakrishnan, an expert on modeling physical forces that influence binding events, have long collaborated within the Physical Sciences in Oncology Network. This large network of physical scientists and engineers focuses on cancer mechanisms and develops new tools and trainee opportunities shared across the U.S. and around the world.

Additional Engineering faculty with growing efforts in the new Center include Lukasz Bugaj, Alex Hughes and Jenny Jiang (BE), Bomyi Lim (CBE), Jennifer Lukes (MEAM) and Vivek Shenoy (Materials Science and Engineering).

Among the PACE Center’s initial research efforts are studies of the genetic and immune mechanisms associated with whether a tumor is solid or liquid and investigations into how physical stresses influence cell signaling.

Becoming a Bioengineer, Both at Home and On Campus

by Erica K. Brockmeier

While the majority of courses remained online this spring, a small number of lab-based undergraduate courses were able to resume limited in-person instruction. One course was BE 310, the second semester of the Bioengineering Modeling, Analysis, and Design lab sequence. Better known as BE-MAD, this junior-year bioengineering course was able to bring students back to the teaching lab safely this spring while adapting its curriculum to keep remote learners engaged with hands-on lab modules at home.

An Essential Step Towards Becoming a Bioengineer

After learning the basics of chemistry, physics, biology, and math during freshman year and studying bioengineering fundamentals throughout sophomore year, BE-MAD is designed to provide essential hands-on experience to bioengineering majors during their junior years. In BE-MAD, students integrate what they’ve learned so far in the classroom to addressing complex, real-world problems by breaking down the silos that exist across different STEM fields.

“Usually what we hear from students is that this BE 309/310 sequence is when they really feel like they are engineers,” says Brian Chow, one of the BE 310 instructors. “They can put what they learn in classes to work in some practical setting and applied context.”

BE-MAD is also an important course to prepare students for senior design and is designed to be a “safe space to fail,” allowing students to build confidence through trial and error within a supportive environment, explains Sevile G. Mannickarottu, director of the educational laboratories. “We’re trying to build skills needed for senior year as well as teaching students how to think critically about problems by pulling together the materials they’ve learned all in one place,” he says. “By senior year, we want them to, when presented with a problem, not be afraid.”

Adapting BE-MAD for Both Remote and Hybrid Instruction

Traditionally, the BE-MAD lab is taught in the George H. Stephenson Foundation Educational Laboratory & Bio-MakerSpace, the primary bioengineering teaching lab, and includes modules on dialysis, drug delivery, insect limb control, microfluidics, cell-cell communication, ECG analysis, and spectroscopy. In the fall, the first lab in the series (BE-309) pivoted to remote learning using video tutorials of lab experiments and providing real data to students for analysis.

This spring, with more aspects of on-campus life able to reopen, the Educational Laboratory staff and BE-MAD instructors developed protocols in collaboration with David Meaney, Penn Engineering senior associate dean and an instructor for BE 309, and Penn’s Environmental Health and Radiation Safety office to safely reopen the teaching lab and Bio-MakerSpace for both BE-310 and for bioengineering senior design students.

The BE-MAD lab was also recreated on Gather.Town, an online video chat platform where students can speak with group members or instructors. Student groups also had their own tables where they could meet virtually to work on data analysis and lab report writing.

To continue to meet the needs of remote students, BE 310 instructor Lukasz Bugaj says that the curriculum was adapted to be two parallel courses—one that could be done entirely at home and the other in-person. The challenge was to adjust the content so that it could be completed either in-person or virtually, and could be switched from in-person to virtual at a moment’s notice because of COVID precautions, all while maximizing the hands-on experience, says Bugaj. “That’s a real credit to the lab staff of Sevile and Michael Patterson, who put a lot of work into revamping this entire class.”

New Faculty Joining Penn Bioengineering

We are thrilled to announce the successful recruitment of three (!) new faculty members to the department. We conducted a national faculty search and could not decide on one — we wanted all three of our finalists!  We are very happy that they chose Penn and think we can provide an amazing environment for their education and research programs.

new faculty hughes
Alex Hughes, Ph.D.

Alex Hughes, Ph.D., will join us in the Spring 2018 semester. Dr. Hughes comes to us from the University of California, San Francisco (UCSF), where he is a postdoctoral fellow. Alex’s research regards determining what he calls the “design rules” underlying how cells assemble into tissues during development, both to better understand these tissues and to engineer methods to build them from scratch

new faculty bugaj
Lukasz Bugaj, Ph.D.

Lukasz Bugaj, Ph.D., will arrive in the Spring 2018 semester. Dr. Bugaj is also coming here from UCSF following a postdoc, and his work is in the field of optogenetics — a scientific process whereby light is used to alter protein conformation, thereby giving one a tool to manipulate cells. In particular, Lukasz’s research has established the ability to induce proteins to cluster ‘on demand’ using light, and he wants to use these and other new technologies he invented to study cell signaling in stem cells and in cancer.

new faculty mitchell
Mike Mitchell, Ph.D.

Mike Mitchell, Ph.D., will also join us in the Spring 2018 semester after finishing his postdoctoral fellowship at MIT in the Langer Lab. In his research, Dr. Mitchell seeks to engineer cells in the bone marrow and blood vessels as a way of gaining control over how and why cancer metastasizes. Mike’s work has already had impressive results in animal models of cancer. His lab will employ tools and concepts from cellular engineering, biomaterials science, and drug delivery to fundamentally understand and therapeutically target complex biological barriers in the body.

In the coming month, we’ll feature podcasts of interview with each of the new faculty members, as well as with Konrad Kording, so be sure to keep an eye out for those.

And to our new faculty, welcome to Penn!
