Human Placenta-derived Stem Cell Transplantation

**Semantic type:** Therapeutic or Preventive Procedure

**Definition:** An adjunctive therapy to umbilical cord blood (UCB) transplantation that is used to augment stem cell engraftment in hematopoietic reconstitution. The process to extract human placenta-derived stem cells (HPDSCs) yields an enriched population of CD34-positive hematopoietic stem cells that, when transplanted in conjunction with UCB stem cells, may provide a novel source for natural killer (NK) cells.

**Synonyms:** - HPDSC Transplantation - Human Placental-derived Stem Cell Transplantation
