AbstractObjectiveTo investigate the effect of eleutheroside injection on the proliferation of bone marrow mesenchymal stem cells (MSCs). Methods MSCs were isolated from rat bone and cultured under same conditions. The proliferation effect of eleutheroside injection on MSCs was detected with MTT and the Brdu marking positive rate of MSCs was detected with immunohistochemical method. Results There were significant difference among four kinds concentration of eleutheroside injection on MSC compared with control group (P 0 [6 s4 y- ]1 D3 b, W / t @, t A8 ?.

5 l" m6 T$ I- s3 W0 p8 e骨髓间充质干细胞( Mesenchymal stem cells,MSC)具有向多种细胞系统分化的潜能,自体获取的骨髓MSC回输后不会发生免疫排斥反应,体外基因转染率高,因此,骨髓MSC已成为组织工程、细胞治疗、基因治疗等方面的研究热点,但骨髓中MSC的含量非常少。我国中药资源丰富,在这些中药中可能有大量的能够促进干细胞增殖、分化的药物。刺五加注射液是临床常用中成药注射剂,能够平补肝肾、益精壮骨,用于肝肾不足所致的短暂性脑缺血发作、脑动脉硬化、脑血栓形成、脑栓塞等症。本研究组通过体外实验研究了刺五加注射液对骨髓间充质干细胞增殖的影响,现报告如下: ! ^3 Z0 T8 u ]5 z) u# C2 m- L1 A, [# V, D# e) v!
