Hematopoietic stem cell transplantation (HSCT), a type of transplantation using multipotent hematopoietic stem cells typically derived from bone marrow, peripheral blood, or that from umbilical cord blood. When your own stem cells are used, it’s called autologous, allogeneic when stem cells are used from a donor, and syngeneic when the stem cells are derived from an identical twin. HSCT is usually reserved for life-threatening conditions like Krabbe disease.
