Abstract
In long-term marrow cultures, proliferation and differentiation of hemopoietic stem cells occurs for several months. Normally, only the most primitive erythroid progenitor cells are produced (the BFU-E). Following treatment with anemic mouse serum (AMS) or normal mouse serum plus erythropoietin, the BFU-E mature into CFU-E, which then go to produce mature nonnucleated red cells. This development is associated with the production of adult type hemoglobin. Furthermore, erythropoiesis and granulopoiesis occur in association with discrete cellular elements of the adherent cell layer in the long-term culture. Following treatment with AMS, erythropoiesis is enhanced while granulopoiesis is depressed, with no apparent competition at the stem cell or progenitor cell level.
