New blood cells are permanently generated from stem cells in the hemopoietically active bone marrow. Pluripotent hematopoietic stem cells have the capacity to selfreplicate and to produce progeny committed to any of the different lineages of blood cells. Little is known about the mechanisms which control the differentiation of the pluripotent stem cells. The glycoprotein hormone erythropoietin stimulates the proliferation and differentiation of progenitor cells committed to the erythrocytic lineage (Fig. 1). |
