ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of panaxadiol saponins component (PDS-C) isolated from total saponins of panax ginseng on proliferation, differentiation and corresponding gene expression profile of megakaryocytes.</p><p><b>METHODS</b>Bone marrow culture of colony forming assay of megakaryocytic progenitor cells (CFU-MK) was observed for the promoting proliferation mediated by PDS-C, and differentiation of megakaryocytic blasts caused by PDS-C was analyzed with flow cytometry in CHRF-288 and Meg-01 cells, as well as proliferation, differentiation-related genes expression profile and protein expression levels were detected by human gene expression microarray and western blot.</p><p><b>RESULTS</b>In response to PDS-C 10, 20 and 50 mg/L, CFU-MK from 10 human bone marrow samples was increased by 28.9%±2.7%, 41.0%±3.2% and 40.5%±2.6% over untreated control, respectively (P <0.01, each). Flow cytometry analysis showed that PDS-C treated CHRF-288 cells and Meg-01 cells significantly increased in CD42b, CD41, TSP and CD36 positive ratio, respectively. PDS-C induced 29 genes up-regulated more than two-fold commonly in both cells detected by human expression microarray representing 4000 known genes. The protein expression levels of ZNF91, c-Fos, BTF3a, GATA-1, RGS2, NDRG2 and RUNX1 were increased with western blot in correspond to microarray results.</p><p><b>CONCLUSION</b>PDS-C as an effective component for hematopoiesis, play the role to enhance proliferation and differentiation of megakaryocytes, also up-regulated expression of proliferation, differentiation-related genes and proteins in vitro.</p>
