Alternative sources of hematopoietic stem cells for bone marrow transplantation and rescue.

ABSTRACT

Hematopoietic stem cells from sources other than medullary bone marrow are being used for experimental and clinical rescue following myeloablative therapy. In this paper we review the cells capable of bone marrow engraftment and the use of orthotopic, cadaveric, peripheral blood, umbilical cord blood, and fetal liver derived stem cells in transplantation.
