Allogeneic CD34-positive Enriched Peripheral Blood Stem Cells

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A preparation of allogeneic CD34+ selected peripheral blood stem cells (PBSCs) that can potentially be used for immune reconstitution purposes. Upon administration of the allogeneic CD34-positive enriched PBSCs after a hematopoietic cell transplantation (HCT), these cells may provide memory T-cell (Tm) recovery and potentially prevent viral infections. They potentially reduce the occurrence of graft-versus-host disease (GvHD) without increasing the risk of graft failure or poor graft function.

**Synonyms:** - Allogeneic CD34+ PBSCs - Allogeneic CD34+-enriched Peripheral Blood Stem Cells - Donor-derived CD34-positive PBSCs
