Penn Bioengineers Create Non-invasive Cartilage Implants for Pediatric Subglottic Stenosis

Bioengineering researchers at Children’s Hospital of Philadelphia are developing a less invasive and quicker method to create cartilage implants as an alternative to the current treatment for severe subglottic stenosis, which occurs in 10 percent of premature infants in the U.S.

Subglottic stenosis is a narrowing of the airway, in response to intubation. Severe cases require laryngotracheal reconstruction that involves grafting cartilage from the rib cage with an invasive surgery. With grant support from the National Institutes of Health, Riccardo Gottardi, PhD, who leads the Bioengineering and Biomaterials (Bio2) Lab at CHOP, is refining a technology called Meniscal Decellularized scaffold (MEND). Working with a porcine model meniscus, the researchers remove blood vessels and elastin fibers to create pathways that allow for recellularization. Dr. Gottardi and his team then harvest ear cartilage progenitor cells (CPCs) with a minimally invasive biopsy, combine them with MEND, and create cartilage implants that could be a substitute for the standard laryngotracheal reconstruction.

This work and similar work on the tympanic membrane earned Paul Gehret, a doctoral student in the Gottardi Lab, the International Society for Biofabrication New Investigator Award and the Wake Forest Institute for Regenerative Medicine Young Investigator Award.  Gehret and Dr. Gottardi accepted the awards at Biofabrication 2022, the International Conference on Biofabrication, in Pisa Italy.

While laryngotracheal reconstruction in the adult population has a success rate of up to 96%, success rates in children range from 75% to 85%, and children often require revision surgery due to a high incidence of restenosis. The procedure also involves major surgery to remove cartilage from the rib cage, which is more difficult for childrens’ smaller bodies.

“Luckily not many children suffer from severe subglottic stenosis, but for those who do, it is really serious,” said Dr. Gottardi, who also is assistant professor in the Department of Pediatrics and Department of Bioengineering at CHOP and the University of Pennsylvania. “With our procedure, we have an easily accessible source for the cartilage and the cells, providing a straightforward and noninvasive treatment option with much potential.”

Riccardo Gottardi is an Assistant Professor in the Department of Pediatrics, Division of Pulmonary Medicine in the Perelman School of Medicine and in the Department of Bioengineering in the School of Engineering and Applied Science. He also holds an appointment in the Children’s Hospital of Philadelphia (CHOP).

Paul Gehret is a Ph.D. student in Bioengineering, an Ashton Fellow and a NSF Fellow. His research focuses on leveraging decellularized cartilage scaffolds and novel cell sources to reconstruct the pediatric airway.

Postdoctoral Fellow Linden Parkes Wins BBRF Young Investigator Grant

Linden Parkes, PhD

The Department of Bioengineering at Penn is thrilled to congratulate Linden Parkes on receiving a Brain & Behavior Research Foundation (BBRF) Young Investigator Grant for 2021-2022. This grant will support Parkes’ continued postdoctoral research under the supervision of Danielle S. Bassett, J. Peter Skirkanich Professor of Bioengineering and Electrical and Systems Engineering in the School of Engineering and Applied Science (SEAS),  Theodore D. Satterthwaite, Associate Professor of Psychiatry in the Perelman School of Medicine (PSOM), and Raquel E. Gur, the Karl and Linda Rickels Professor of Psychiatry in PSOM.

Originally from Australia, Parkes did his undergraduate B.Sc. (Hons.) in Psychology and Psychophysiology at the Swinburne University of Technology in Melbourne. He went on to receive his Ph.D. in Neuroscience from the Turner Institute for Brain and Mental Health at Monash University (also in Melbourne) under the supervision of Murat Yucel, Professor of Psychology, Alex Fornito, Professor of Psychology, and Ben Fulcher, Senior Lecturer in the School of Physics at the University of Sydney. After finishing his doctorate, Parkes moved to Philadelphia to take up a position as a postdoctoral fellow in Danielle Bassett’s Complex Systems Lab.

Parkes will use the BBRF’s support to continue his research examining the link between the symptoms of mental illness and the brain. In particular, he seeks to uncover how individual patterns of abnormal neurodevelopment link to, and predict, the emergence of psychosis symptoms through childhood and adolescence using longitudinal data. In turn, Parkes’ work will discover prognostic biomarkers for the psychosis spectrum that will help inform clinical outcome tracking.

“I am honored to have been selected for a Young Investigator Grant from the BBRF this year,” Parkes says. “This award will support me to conduct research that I believe will make real inroads into understanding the pathways that link abnormalities in neurodevelopment to the symptoms of psychosis. I feel grateful for the opportunity to complete my postdoctoral training at Penn. Penn has connected me with wonderful people who I’m sure will be lifelong mentors, colleagues, and peers.”

The BBRF Young Investigator Grants are valued at more than $10.3 million and are awarded annually to 150 of the world’s most promising young scientists to support the work of early career investigators with innovative ideas for groundbreaking neurobiological research seeking to identify causes, improve treatments, and develop prevention strategies for psychiatric disorders.
