Stem Cell Therapeutic and Research Reauthorization Act of 2026

This bill reauthorizes the Stem Cell Therapeutic and Research Act of 2005, which funds the C.W. Bill Young Cell Transplantation Program that provides cord blood transplants to patients with certain blood and immune system disorders. It extends the program's funding through fiscal year 2031, allocating $31 million for 2026 and $33 million annually for 2027 through 2031. The legislation also updates the cord blood inventory deadline from 2026 to 2031, allowing the National Marrow Donor Program to maintain and manage the national cord blood registry for an additional five years. These changes directly affect patients requiring cord blood transplants, healthcare providers administering these treatments, and the organizations managing the cord blood inventory system.
