To evaluate the effects of a novel 2-aminosteroid, 2-(4'-methyl-1'-piperazinyl)-3alpha-hydroxyl-5alpha-androstane-17-one (KH), on in vitro murine WEHI-3B leukemia cells, semisolid colony culture, MTT assay, morphological examination, NBT reduction, NSAE test and ACP assay were used to determine proliferation and differentiation. It was found that the growth(More)
To evaluate the effect of a novel aminosteroid on murine myelomonocytic leukemia, BALB/c mice were treated by the novel aminosteroid for 7 days after receiving 1 x 10(6) WEHI-3B(myelomonocytic leukemia) cells intraperitoneally. The counts and classification of white blood cells obtained from tail blood were determined on the day before transplanting WEHI-3B(More)
In the present study, the effects of murine bone marrow endothelial cell conditioned medium (ECM) combined with flt3 ligand (FL) or/and thrombopoietin (TPO) on the proliferation of HPP-CFC and CFU-GM were investigated. Both ECM and the concentrated retentate of ECM (MW>10 kD) promoted the growth of CFU-GM and HPP-CFC, and this promoting effect was further(More)
To explore the distinct background of bone marrow and embryonic yolk sac hematopoiesis performance, serum free murine yolk sac endothelial cell and bone marrow endothelial cell conditioned medium were compared for their effects on the development profiles of yolk sac hematopoietic stem/progenitor cells. The mRNAs expression techniques were applied to(More)
OBJECTIVE To evaluate the effect of a novel aminosteroid(KH) on WEHI-3B cells. METHODS The effects and mechanism of KH on proliferation, differentiation and apoptosis of WEHI-3B cells in vitro were studied by semi-solid colony culture, MTT assay, morphologic examination, NBT reduction test, NSE assay, DNA fragmentation in gel electrophoresis and RT-PCR of(More)
