The effect of vitamin A deficiency (VAD) on the proliferation of erythroid progenitor cells and its mechanism were studied by using the culture of hematopoietic progentor cells and assaying biological activation of hematopoietic growth factor (HGF). The results indicated that the proliferation. of DFU - E in vitro was decreased 27%(P<0.05) in VAU rats as compared with the coantrol.BFU - E treated by using the spleen cell and bone marrow stromal cell conditioned media with VAD rats also decreased 19% and 30% respectively (P< 0.05) compared with the control. It suggests that erythropoiesis in VAD rats was inhibited by the stromal cell in hematopoieic inductive microenvironment and lymphocyte to produce some HGF (such as IL3
GM - CSF and so on)
