Breakfast Club Seminar Series
Location: Parker H. Petit Institute for Bioengineering & Bioscience, Rm. 1128(404) 894-6228
Location Phone: (404) 894-6228
The IBB Breakfast Club seminar series was started with the spirit of the Institute's interdisciplinary mission in mind and started to feature local IBB faculty member's research in a seminar format. Faculty are often asked to speak at other universities and conferences, but rarely present at their home institution, this seminar series is an attempt to close that gap. The IBB Breakfast Club is open to anyone in the bio-community.

"Hepatopancreatic Programming/reprogramming in a Zebrafish Model System"
Chong Shin, PhD
School of Biology
Worldwide, liver failure and diabetes mellitus are the leading cause of morbidity and mortality. The therapeutic restoration of hepatocyte and β-cell mass would support the functions of a failed liver and pancreas. One approach to restoration is the transplantation of exogenous hepatocytes and β-cells generated from pluripotent stem cells. Despite notable progress, the resulting cells often fail to achieve complete function. Therefore, deciphering the activated signaling pathways and their cross-regulatory interactions during embryogenesis is crucial. A second approach to restoration is the stimulation of endogenous repair mechanisms. Although mammals have a limited capacity for regeneration, they may retain developmental and/or ancestral pathways that are typically quiescent in adults. By studying the recovery in other vertebrates not only with homologous liver and pancreas structure but also with significant capacity for regeneration, we can unveil key repair markers and/or pathways. We use the zebrafish system, an experimental model that offers the functional live imaging ability, high-throughput capacity, and single-cell level manipulability, within a vertebrate system that faithfully recapitulates the genetic control of mammalian hepatogenesis and pancreatogenesis.
