摘要 目的:探讨脐血中性粒细胞上清液对脐带间充质干细胞(umbilical cord mesenchymal stem cells,UC-MSCs)增殖、白细胞介素-6(IL-6)分泌的影响。方法:分离脐血中性粒细胞,UC-MSCs在不同浓度的中性粒细胞上清液中培养为实验组,UC-MSCs和中性粒细胞的比例分别为1∶1、1∶10、1∶50、1∶100,UC-MSCs单独培养为对照组(1∶0)。在分别培养18h和40h后,用MTT法检测各组增殖,评价不同组间的增殖情况,用ELISA方法检测不同组间培养上清IL-6水平。结果:1∶50和1∶100组UC-MSCs生长受到抑制(P<0.05),18h和40h差异无显著性(P>0.05)。1∶50实验组中,IL-6的分泌水平低于1∶0和1∶1实验组(P<0.05)。结论:高浓度的脐血中性粒细胞上清液抑制UC-MSCs的增殖。高浓度的脐血中性粒细胞的上清液抑制人UC-MSCs分泌IL-6。
