Curing bladder cancer by replacing corrupted urothelium with differentiated hES cells
Research Objective The goal of the proposed research is to use human embryonic stem cells to generate bladder epithelial progenitor cells that can be used to replace a cancerous bladder epithelium in vivo. Impact The long-term goal of the proposed research is to cure bladder cancer. Successful completion of this work may indicate that transplantation […]
Autologous iPSC-based therapy for radiation induced bladder injury
Research Objective To explore if iPSC-based therapy can prevent bladder damage due to radiation therapy, thereby limiting the unintended consequences of treatments for prostate, gynecologic and colorectal cancers. Impact This therapy impacts cancer survivors by preventing the permanent debilitating urinary symptoms due to radiation therapy. Currently there are no therapies to prevent radiation bladder damage. […]
