The aim of this study was to investigate the mechanism underlying the effects of Astragalus membranaceus injection (AMI) on myelopoiesis in myelosuppressed mice. At 72 h after cyclophosphamide injection (250 mg/kg), the mice were administered AMI (500 mg/kg) intraperitoneally for 6 consecutive days or an equivalent volume of saline as a control. Murine colony-forming unit-fibroblast (CFU-F) formation, production of IL-6 and GM-CSF by bone marrow stromal cells (BMSC), and bcl-2 protein and mRNA expression in BMSC were measured by CFU-F assay, ELISA, immunohistochemistry and in situ hybridization. The results indicated that AMI improved the hematopoietic microenvironment by enhancing the BMSC survival and proliferation of CFU-F, production of IL-6 as well as GM-CSF by BMSC and bcl-2 protein and mRNA expression in BMSC, which promoted myelopoiesis. The data may provide a mechanistic basis for applying this ancient Chinese herb to promote hematopoiesis as an efficacious adjuvant therapy against myelosuppression induced by anti-cancer therapy.
