摘要：

背景：研究表明，黄芪可促进骨髓间充质干细胞向神经元方向分化。
目的：观察黄芪注射液对大鼠骨髓间充质干细胞活性的影响。
方法：分离、培养SD大鼠骨髓间充质干细胞。取第4代细胞，以50，100，200 g/L的黄芪注射液作用5，12，24 h，MTT实验观测黄芪注射液对大鼠骨髓间充质干细胞活性的影响。
结果与结论：原代培养细胞在8~10 d后接近 80%~90% 融合状态，可进行传代。传至第3代基本完成细胞的纯化。MTT实验显示，伴随黄芪注射液浓度升高和作用时间延长，骨髓间充质干细胞活性逐渐升高，出现类似神经细胞形状改变，其间差异有显著性意义 (P < 0.05)。提示黄芪不仅可以诱导骨髓间充质干细胞分化，并且对细胞具有营养作用。

Abstract:

BACKGROUND: Astragalus mongholicus contributes to the differentiation of bone marrow mesenchymal stem cells (BMSCs) into neurons.
OBJECTIVE: To observe effects of astragalus mongholicus on viability of rat BMSCs.
METHODS: BMSCs of Sprague Dawley rats were isolated and cultured. The fourth passage of cells were treated with 50, 100,
200 g/L astragalus mongholicus for 5, 12, 24 hours respectively. BMSCs viability changes were observed by MTT assay after they were induced by astragalus mongholicus.
RESULTS AND CONCLUSION: Primarily cultured cells were closed to 80%-90% fusion status after 8-10 days culture and they could be passaged. The third generation had been purified on the whole. The results from MTT assay showed that the BMSCs viability would be increased with the increased concentration of astragalus mongholicus and the prolonged action time. Morphological changes in neural cells appeared. There were significant differences between groups (P < 0.05). These indicate that astragalus mongholicus can induce the differentiation of BMSCs and nourish cells.
