Multipotent neural stem cell (MNSC) progeny are induced to generate cells
of the hematopoietic system by placing the MNSC progeny in a hematopoietic-inducing
environment. The hematopoietic-inducing environment can be either ex vivo or in
vivo. A mammal's circulatory system provides an in vivo environment that can induce
xenogeneic, allogeneic, or autologous MNSC progeny to generate a full complement
of hematopoietic cells. Transplantation of MNSC progeny provides an alternative
to bone marrow and hematopoietic stem cell transplantation to treat blood-related disorders.
