Two Penn Bioengineering Professors have received awards in the 7th Annual Celebration of Innovation from the Penn Center for Innovation (PCI).

Dongeun (Dan) Huh, Associate Professor in the Department of Bioengineering, was named the 2022 Inventor of the Year. D. Kacy Cullen, Associate Professor of Neurosurgery with a secondary appointment in Bioengineering, accepted the Deal of the Year Award on behalf of his company Innervace along with Co-Scientific Founder Douglas H. Smith, Robert A. Groff Professor of Teaching and Research in Neurosurgery in the Perelman School of Medicine.

PCI is interdisciplinary center for technology commercialization and startups in the Penn community. Their 7th Annual Celebration, held on December 6, 2022 at the Singh Center for Nanotechnology, honored Penn researchers and inventors whose achievements were a particular highlight of the fiscal year.

Huh was honored in recognition of his “extraordinary innovations in bioengineering tools.” The Huh Biologically Inspired Engineering Systems Laboratory (BIOLines) Laboratory is a leader in tissue engineering and cell-based smart biomedical devices, particularly in the “lab-on-a-chip” field of devices which can approximate the functioning of organs. Their research has been featured by the National Science Foundation (NSF, video below) and Wired, and has received a competitive Chan Zuckerberg Initiative (CZI) grant. Most recently, their “implantation-on-a-chip” technology has been used to better understand early-stage pregnancy. Huh and former lab member Andrei Georgescu (Ph.D. in Bioengineering, 2021) founded the spinoff company Vivodyne to bring this organ-on-a-chip technology to the industry sector. Fast Company included Vivodyne in a list of “most innovative” companies.

Innervace, represented by Cullen and Smith, took home the Deal of the Year award in recognition of its “successful Series A funding.” Innervace is another Penn spinoff which develops “anatomically inspired living scaffolds for brain pathway reconstruction.” Innervace raised up to $40 million in Series A financing to “accelerate a new cell therapy modality for the treatment of neurological disorders.” The Cullen Lab at Penn Medicine combines neuroengineering, regenerative medicine, and the study of neurotrauma to improve understanding of neural injury and develop cutting-edge neural tissue engineering-based treatments to promote regeneration and restore function.

2022 Penn iGEM Team Wins Gold Medal in Grand Jamboree

The 2022 iGEM team from left to right: June Ahn, Shreya Villimanalan, Adiva Daniar, Wangari Mbuthia, Cristina Perez and Moses Zeidan.

Congratulations to the 2022 University of Pennsylvania iGEM Team who took home a gold medal in the iGEM Grand Jamboree. This international competition of multidisciplinary teams of graduate and undergraduate students presenting original projects in synthetic biology culminated in the in-person Jamboree event held in Paris, France in October 2022. Over 370 judges awarded prizes and medals to the 350+ teams representing over 40 countries.

The 2022 Penn team was awarded a Gold Medal for their project “Photocreate,” a toolbox to control intercellular communication using optogenetics. Their plasmid constructs are designed to control protein secretion, display and shedding using a photocleavable protein, Phocl. The full abstract reads:

Intercellular communication is primarily studied using synthetic protein-level circuits. These circuits currently lack the spatial and temporal control necessary for targeted and time-sensitive applications. To address this gap, we developed Photocrete, a toolbox of protein constructs for light-inducible control of protein display, secretion, and shedding. We expanded upon RELEASE (Vlahos et al.), a modular and generalizable protein circuit which utilizes an ER retention motif and an exogenous protease to control protein secretion. We optogenetically modified RELEASE by replacing different components with the photocleavable protein PhoCl, allowing us to control the mammalian secretion pathway at distinct nodes with finely-tuned light administration regimens. Preliminary results indicate integration of Photocrete into the secretion pathway, but more research is necessary to determine optimal light administration settings. The potential for high spatial and temporal control of Photocrete could allow researchers to perform various signaling studies and develop therapeutics at a new level of precision.

The 2022 iGEM team includes undergraduates June Ahn (B.S. in Biochemistry, Physics and Nutrition), Adiva Daniar (B.S.E. in Bioengineering, minor in Engineering Entrepreneurship), Wangari Mbuthia (B.S.E. in Bioengineering), Cristina Perez (B.S.E. in Bioengineering, minor in Physics), Shreya Vallimanalan (B.S.E. in Bioengineering, minor in Computational Neuroscience), an d Moses Zeidan (B.S.E. in Bioengineering, minor in Chemistry and Spanish). They were mentored by graduate students David Gonzalez-Martinez, Gabrielle Ho, Zikang Huang, and Will Benman. Their faculty advisor is Lukasz Bugaj, Assistant Professor in Bioengineering.

‘Organ-on-a-Chip’ Device Provides New Insights into Early-Stage Pregnancy

by Scott Harris

Dan Huh’s BIOLines Lab develops several different kinds of organ-on-a-chip systems, such as this blinking-eye-on-a-chip.

If you’d read about it in a science fiction novel, you might not have believed it. Human organs and organ systems — from lungs to blood vessels to blinking eyes — bio-miniaturized and stored on a plastic chip no larger than a matchbook.

But that’s the breathing, blinking reality at the Biologically Inspired Engineering Systems (BIOLines) Laboratory in the Department of Bioengineering in the School of Engineering and Applied Sciences at the University of Pennsylvania, a bona fide pioneer of what is now widely known as “organ-on-a-chip” technology. Proponents hope these devices can one day help scientists around the world learn more about the body’s inner workings and ultimately improve disease prevention and treatment.

“The century-old practice of cell culture is to grow living cells isolated from the human body in hard plastic dishes and keep them bathed in copious amounts of culture media under static conditions, and that is drastically different than the complex, dynamic environment of native tissues in which these cell reside,” said Dan Dongeun Huh, Ph.D., BIOLines’ principal investigator and an associate professor of Bioengineering in Penn’s School of Engineering and Applied Science. “What makes this organ-on-a-chip technology so unique and powerful is that it enables us to reverse-engineer living human tissues using microengineered devices and mimic their intricate biological interactions and physiological functions in ways that have not been possible using traditional cell culture techniques. This represents a major advance in our ability to model and understand the inner workings of complex physiological systems in the human body.”

Generally speaking, organ-on-a-chip devices are made of clear silicone rubber — the same material used to make contact lenses — and can vary in size and design. Embedded within are microfabricated three-dimensional chambers lined with different human cell types, arranged and propagated to ultimately form a structure complex enough to actually mimic the essential elements of a functioning organ.

With partners at the Perelman School of Medicine, BIOLines recently developed a newer variation of the organ-on-a-chip: one that replicates the interface between maternal tissue and the cells of the placenta at the critical moments in early pregnancy when the embryo is implanting in the uterus. Huh and Penn Medicine physicians led a study using the “implantation-on-a-chip” to observe things that would otherwise have been virtually unobservable.

The study findings appeared this spring in the journal Nature Communications.

Twin academics Dani S. Basset, J. Peter Skirkanich Professor and director of the Complex Systems Lab, and Perry Zurn, a professor of philosophy at American University, were recently featured as guests on NPR radio show “Detroit Today” to discuss their new book, “Curious Mind: The Power of Connection.”

In their book, Basset and Zurn draw on their previous research, as well as an expansive network of ideas from philosophy, history, education and art to explore how and why people experience curiosity, as well as the different types it can take.

Basset, who holds appointments in the Departments of Bioengineering and Electrical and Systems Engineering, as well as the Department of Physics and Astronomy in Penn Arts & Science, and the Departments of Neuroscience and Psychiatry in Penn Perelman’s School of Medicine, and Zurn spoke with “Detroit Today” producer Sam Corey about what types of things make people curious, and how to stimulate more curiosity in our everyday lives.

According to the twin experts, curiosity is not a standalone facet of one’s personality. Basset and Zurn’s work has shown that a person’s capacity for inquiry is very much tied to the overall state of their health.

“There’s a lot of scientific research focusing on intellectual humility and also openness to ideas,” says Bassett. “And there are really interesting relationships between someone’s openness to ideas, someone’s intellectual humility and their curiosity and also their wellbeing or flourishing,”

Listen to “What makes people curious and how to encourage the act” at “Detroit Today.”

Register for a book signing event for “Curious Minds: The Power of Connection,” on Friday, December 9th at the Penn Bookstore.
