摘要: 目的 探讨水通道蛋白1(AQP1)在人羊膜间充质干细胞(hAMSCs)迁移中的作用。方法 免疫荧光染色、RT-qPCR及Western blot检测hAMSCs AQP1的表达,siRNA干扰AQP1后,应用Transwell小室检测hAMSCs的迁移能力。结果 hAMSCs细胞膜上AQP1表达阳性。siRNA干扰AQP1 48h后AQP1 mRNA表达水平降低60.13%; AQP1的蛋白表达水平降低40.42%。siRNA干扰组穿过细胞数目为23.7±1.45显著低于对照组的33.15±1.15(P<0.01)。 结论 AQP1促进人羊膜间充质干细胞的迁移,推测AQP1参与创伤的修复过程。

Abstract: Objective To investigate the effect of aquaporin 1 (AQP1) on human amniotic mesenchymal stem cells (hAMSCs) migration. Methods By immunofluorescence staining, RT-qPCR and Western blot, expression of AQP1 was detected on hAMSCs and migration ability of hAMSCs after siRNA interference was assessed with Transwell. Results The expression of AQP1 on hAMSCs was identified on membrance. After 48 hours interference, the expression of AQP1 was reduced by 60.13% for mRNA level and 40.42%for protein level. The cell numbers through the menberane of control group vs AQP1 siRNA group was signature reduction from 33.15±1.15 to 23.7±1.45, P<0.01. Conclusion AQP1 promoted migration of hAMSCs and involved in wound repair process.

Key words: AQP1, cell migration, human amniotic mesenchymal stem cells, wound repair
