Objective: To study the effect of Weiganli (维肝力)on bone marrow hemopoiesis. Methods: The effects of Weiganli on the peripheral blood picture and the number of bone marrow nucleated cells (BMCs) were observed in myelosuppressed anemic model mice, and the effects of Weiganli on the growth of colony forming unit-granulocyte macrophage (CFU-GM), colony forming unit-erythroid (CFU-E), burst forming unit-erythroid (BFU-E), colony forming unit-megkaryocyte (CFU-Meg) were investigated by in vitro cell culture technique. The hemopoietic stem cells (HSCs, c-kit+) in bone marrow were double stained with fluorescent antibody PE-C-Kit and FITC-CD45, and the HSCs (c-kit+) were counted by flow cytometer with CD45/SSC (side scatter) gating. Results: Peripheral blood cell counts and the number of BMCs were significantly improved after Weiganli administration; and bone marrow hemopoietic stem/progenitor cells were significantly increased. Conclusion: Weiganli can effectively promote the recovery of hemopoietic function in the myelosuppressed anemic mice. Objective: To study the effect of Weiganli on bone marrow hemopoiesis.
