摘要
目的:观察复方浙贝母药物血清对人脐带间质干细胞(MSCs)增殖抑制和凋亡影响。方法:MTT法测不同剂量组复方浙贝药物血清对人脐带MSCs的抑制率;Annexin-V/PI双染经流式细胞仪(FCM)定量检测复方浙贝药物血清诱导人脐带MSCs细胞早期凋亡率。结果:①高、中、低剂量组复方浙贝药物血清对人脐带MSCs细胞增殖抑制率分别为:3.88%、-3.37%和4.38%;含阿霉素血清组为47.88%。②经FCM双荧光法检测复方浙贝不同浓度药物血清诱导人脐带MSCs细胞早期凋亡百分比不同:空白组为35.19%,低剂量组为1.63%,中剂量组为1.19%,高剂量组为1.70%。结论:复方浙贝药物血清能部分促进人脐带MSCs的增殖(中剂量组),并保护人脐带MSCs的凋亡损伤。
