Abstract

Abstract Embryonic stem (ES) cells are capable of unlimited self-renewal and have the ability to give rise to all tissue types in the body. Recently, tissue-specific stem cells such as bone marrow cells have also been found to be capable of multilineage differentiation into cells of various nonblood tissues. Umbilical cord blood hematopoietic stem cells have been shown to be as effective as bone marrow stem cells for rebuilding the hematopoietic system and differentiating into nonblood cell types. This observation raises the exciting possibility of replacing human ES cells for tissue and cell therapeutics with umbilical cord blood hematopoietic stem cells that are normally discarded with the placenta after delivery.
