Effect of Ginseng polysaccharide on the proliferation and differentiation of granulocyte-monocyte progenitor cells

DAI Qin,WANG Ya-ping,ZHOU Kai-zhao,et al. (The first Afiliated Hospital of the Medical Science University of Chongqing, Hematology Department, College of Basic Medical Sciences, Chongqing 400016,China)  
To study the effect of Ginseng polysaccharide(GPS) on modulation of human granulocytopoiesis and monocytopoiesis. The results indicated that ①granulocyte-macrophage colony stimulating factor, GPS markedly promoted the colony formation of CFU-GM ex vivo;②Thymocytes, splenocytes or bone marrow stromal cells conditioned media supernatant stimulated by GPS also promoted the colony formation of CFU-GM;③Thymocytes, splenocytes or bone marrow stromal cells induced by GPS expressed much more GM-CSF than that of control group. All results demonstrated that GPS directly and/or indirectly stimulated cells such as lymphocytes, bone marrow stromal cells in hematopoietic microenvironment and induced them to secrete GM-CSF and other hematopoietic regulating factors which in turn promoted the colony formation of CFU-GM. This may be one of the biological mechanisms for antianemic and regulating immunofunction of GPS.
