The primary purpose of this protocol is to incorporate all the NMDP/CIBMTR requirements for securing data and blood samples on recipients whose transplant was facilitated by NMDP/CIBMTR here at NIH as well as TED (Transplant Essential Data) level data submission for NIAID Allogeneic recipient patients and their donors. This protocol will include patients at the NIH that have enrolled in an NIH IRB approved protocol to receive matched unrelated donor (MUD) HSC transplants or cord blood transplants facilitated by the NMDP/CIBMTR. It may also include patients that have undergone a MUD transplant at another approved transplant center but need to receive additional blood products from the donor while at NIH after completing a transplant center transfer.
