摘要 目的:探讨缸鱼软骨多糖(RCG)对人脐静脉内皮细胞形成新生血管的作用。方法:原代培养人脐静脉内皮细胞,实验分为生理氯化钠溶液(NS)对照组、RCG100,50,25,10,2g·L^-1组和阳性对照鲨鱼软骨多糖(SCG,50g·L^-1)组。采用MTT法检测RCG对HUVEC增殖的影响,流式细胞仪检测RCG对HUVEC细胞周期的影响;并观察RCG对HUVEC迁移及小管形成的作用。结果:10~100g·L^-1RCG可明显抑制HUVEC的体外增殖,IC50为62.93g·L^-1。流式细胞仪检测表明,RCG阻止HUVEC在G2/M期。10—100g·L^-1RCG明显抑制HUVEC迁移和小管形成。结论:RCG具有良好的体外抗血管生成活性。 Objective:To investigate the effect of Ray cartilage glycosaminoglycans (RCG) on angiogenesis in cultured human umbilical endothelial cells ( HUVEC). Methods: The primary cultured endothelial cells of human umbilical vein were treated with RCG (100,50,25,10,2 g·L^-1) , shark cartilage glycosaminoglycans (SCG, 50 g·L^-1) or saline. The effect of RCG in HUVEC was evaluated by MTT reduction assay, and by detecting cell migration and capillary formation. The cell cycle of HUVEC was determined by flow cytometry. Results:RCG at 10 - 100 g·L^-1 obviously inhibited the proliferation of HUVEC with an IC50 value of 62.93 g·L^-1, blocked HUVEC in G2/M phase, and strongly inhibited the migration and capillary formation of HUVEC in a concentration-dependent manner. As compared with same concentration of SCG, no differences were found in the inhibition of the proliferation, migration and capillary formation in HUVEC. Conclusions: RCG exerts a potent anti-angiogenic effect in vitro.
