Dr. Stephen Redenti, Professor of Biochemistry and Molecular Biology at The City University of New York, provides an overview of critical signaling processes that can shed light on retinal health and the origins of degenerative retinal disease. Dr. Redenti explores how decades of research into the biochemistry of tumor metastasis is now informing novel therapeutic approaches that aim to improve the success of stem cell therapies for Retinitis Pigmentosa and other ophthalmic diseases.
