The effect of erythroid differentiation factor (EDF) on the colony formation of erythroid cells (CFU-E and BFU-E) inhibited by the sera from the patients with chronic renal failure (CRF) was evaluated by methylcellulose assay. EDF restored the inhibited formation of CFU-E colony irrespective of the absence or presence of the accessory cells. In addition, EDF was considered to recover BFU-E colony formation through the burst promoting activity (BPA) secreted by the adherent cells. A suicide experiment using 3H-thymidine revealed that EDF acted to induce BFU-E from resting phase to S phase of the cell cycle. Moreover, the number of circulating BFU-E and the secretion of BPA by the mononuclear cells, both of which were significantly low in CRF patients, were also moderately increased by the addition of EDF. These data suggest that EDF could be utilized as a therapeutic agent for pathogenetic factors except hypoproduction of erythropoietin on the anemia of the patients with CRF.

UI	MeSH Term	Description	Entries
D007265	Inhibins	Glycoproteins that inhibit pituitary FOLLICLE STIMULATING HORMONE secretion. Inhibins are secreted by the Sertoli cells of the testes, the granulosa cells of the ovarian follicles, the placenta, and other tissues. Inhibins and ACTIVINS are modulators of FOLLICLE STIMULATING HORMONE secretions; both groups belong to the TGF-beta superfamily, as the TRANSFORMING GROWTH FACTOR BETA. Inhibins consist of a disulfide-linked heterodimer with a unique alpha linked to either a beta A or a beta B subunit to form inhibin A or inhibin B, respectively	Female Inhibin,Inhibin,Inhibin-F,Inhibins, Female,Inhibins, Testicular,Ovarian Inhibin,Testicular Inhibin,Female Inhibins,Inhibin F,Inhibin, Female,Inhibin, Ovarian,Inhibin, Testicular,Testicular Inhibins
D007676	Kidney Failure, Chronic	The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.
