Host: Prof. Michael Brand (CRTD)

Abstract:

Several animals have the ability to regenerate parts of their eye if damaged or removed. Salamanders can regenerate their lenses completely and functionally at any stage of their lifetime by reprogramming pigmented cells of their iris. On the other hand, embryonic chicks can regenerate their retinas if removed by reprogramming retina pigmented epithelial cells. We are dissecting the molecular mechanisms involved in the reprogramming process in both model organisms and moving forward to apply this information towards human iPSC modeling systems. Our work will contribute important information that can help develop therapies for the many blinding diseases that currently rip the sight of many people around the world.
