Change to the Definition of “Human Organ” Under Section 301 of the National Organ Transplant Act of 1984; Withdrawal

This document withdraws a proposed rule published in the Federal Register on October 2, 2013. The proposed rule sought public comment on the proposed change in the definition of ``human organ'' in section 301 of the National Organ and Transplant Act of 1984, as amended, (NOTA) to explicitly incorporate hematopoietic stem cells within peripheral blood in the definition of ``bone marrow.'' HHS received over 500 comments on the proposed rule. Given the number of substantive comments, at this time HHS has decided to consider the issue further and may issue an NPRM in the future.
