摘要：

背景：近年来，对传统单味中药有效成分、复方中药及含药血清调控骨髓间充质干细胞增殖与分化作用的研究已有报道，但鲜有涉及到机制的研究。
目的：观察黄精含药血清体外对骨髓间充质干细胞增殖的影响，并分析其作用途径与机制。
方法：雄性SD大鼠用于骨髓间充质干细胞的提取；雌性SD大鼠以中药水溶液灌胃后定时取血制备含药血清。全骨髓贴壁法分离培养大鼠骨髓间充质干细胞，将传至P3代的细胞，制备成单细胞悬液接种于96孔培养板后，分别加入黄精含药血清及空白血清，各组血清浓度分别为培养液体积的5%，10%，15%，20%，25%及30%。MTT法检测黄精含药血清对骨髓间充质干细胞增殖的影响；RT-PCR检测各细胞因子mRNA表达；实时PCR检测粒细胞集落刺激因子mRNA表达。
结果与结论：与空白血清组相比，体积分数10%的黄精含药血清具有明显促进骨髓间充质干细胞增殖的作用(P < 0.05)，并显著促进粒细胞集落刺激因子mRNA的表达(P < 0.05)。提示体积分数10%的黄精含药血清具有促进骨髓间充质干细胞增殖的作用，可能与其促进粒细胞集落刺激因子mRNA表达有关。

Abstract:

BACKGROUND: Current studies focus on the observation of single or complex Chinese medicine and serum containing drug on bone marrow mesenchymal stem cells (BMSCs) proliferation and differentiation, but few reports have addressed the mechanisms.
OBJECTIVE: To investigate the effect of polygonatum medicated serum on BMSCs proliferation in vitro, and to analyze its action pathway and mechanism.
METHODS: Male Sprague-Dawley rats were used for the isolation of BMSCs cells; the serum of female Sprague-Dawley rats was obtained after intragastric administration with medicine water solution. Rat BMSCs were isolated and purified by whole bone marrow adherent method, purified by trypsin. The third passage of BMSCs were prepared into single cell suspension, and incubated in the 96-well culture plate. The experimental group was added polygonatum medicated serum, while the control group added blank serum at concentration of 5%, 10%, 15%, 20%, 25%, 30%. The polygonatum medicated serum-induced proliferation effect on BMSCs was detected by MTT assay. Different cytokine mRNA expression was measured by RT-PCR. Granulocyte colony-stimulating factor mRNA expression was analyzed by real-time PCR.
RESULTS AND CONCLUSION: Compare with the blank serum group, 10% polygonatum medicated serum significantly promoted the proliferation of BMSCs (P < 0.05), and significantly improved the expression of granulocyte colony-stimulating factor mRNA and protein (P < 0.05). Results suggest that 10% polygonatum medicated serum can promote proliferation of BMSCs, and the mechanism involves the stimulation of granulocyte colony-stimulating factor mRNA expression.
