May 23, 2025. Lenore von Krusenstiern, MD, PhD, at BlueRock Therapeutics talks to host Ben Shaberman about the company's clinical trial for a photoreceptor replacement therapy for people with inherited retinal conditions such as retinitis pigmentosa and cone-rod dystrophy. The approach, which uses induced pluripotent stem cells to develop photoreceptor precursors, comes out of the lab of stem cell pioneer David Gamm, MD, PhD, University of Wisconsin-Madison.
