Abstract:
BACKGROUND:It is shown in past researches that total saponin of ginseng has the effect of promoting multiplication of bone marrow hematopoietic stem cells and progenitor cells in vitro, and promoting secretion of bone marrow hemotopoietic factors, however there has been little researches on the effect of multiplication of bone marrow stromal cells.OBJECTIVE: To investigate the effect of ginsenoside Rg1 on pig's bone marrow stromal cells multiplication in vitro.DESIGN: A controlled observation.SETTING:Department of Cardiology and Department of Dermotology,First Affiliated Hospital, Nanjing Medical University; Department of Pharmacology, Nanjing Medical University.MATERIALS: The experiment was conducted at the Cardiovascular Pharmaceutical Laboratory of Nanjing Medical University from January 2002 to February 2003. The experimental pigs ahd the powder of ginsenoside Rg1were chosen METHODS :The bone marrow stromal cells cultured in vitro were divided as control and experimental groups. For experimental group insenoside Rg1 in different concentrations (10-7,5×10-7,10-6,5×104 mol/L)were added for induction culture, and for control group the media of the same volume was added. The multiplication conditions of bone marrow stromal cells were respectively detected by fibroblast colony forming in vitro, tritiated thymidine {[3H]TdR} incorporation and MTT.MAIN OUTCOME MEASURES: ① The effect of ginsenoside Rgl on the fibroblast colony forming units of bone marrow stromal cells in vitro. ②The effect of ginsenoside Rg1 on [3H]TdR incorporation of bone marrow stromal cells. ③ The effect of ginsenoside Rg1 on bone marrow stromal cells multiplication detected by MTT.RESULTS:① The effect of ginsenoside Rg1 on the fibroblast colony forming units of bone marrow stromal cells in vitro: The numbers of units in experimental group were all higher than that in control group (P ＜ 0.05-P ＜ 0.01),especially obvious in (5-50)×10-7 mol/L experimental group, reaching peak in the concentration being 10-6 mol/L. ② The effect of ginseno side Rg1 on [3H]TdR incorporation of bone marrow stromalcells: As the concentration of ginsenoside Rg1 was 10-6 mol/L, the [3H]TdR incorporation efficiency of bone marrow stromal cells was obviously higher that that in control group (P ＜ 0.05-P ＜ 0.01), and the effect was enhanced as the dosage increased. ③ The effect of ginsenoside Rgl on bone marrow stromal cells multiplication detected by MTT: The value of absorbance in experimental group was obviously higher than that in control group (P ＜ 0.05-P ＜ 0.01), and it was dose-dependent. CONCLUSION: Ginsenoside Rg1 had an effect of multiplication on pig's bone marrow stromal cells in vitro, and it was dose-dependent.
