摘要:

背景:间充质干细胞具有向炎症损伤部位和肿瘤组织特异性趋化的特性,深入研究间充质干细胞对肿瘤细胞生长增殖的影响成为亟需解决的问题。
目的:探讨人脐带间充质干细胞对宫颈癌Hela细胞增殖特性的影响。
方法:将不同细胞数的人脐带间充质干细胞或不同质量浓度的人脐带间充质干细胞条件培养基与宫颈癌Hela细胞共培养3 d,CCK-8检测Hela细胞的增殖抑制情况。
结果与结论:Hela细胞与人脐带间充质干细胞比例分别为1︰3、1︰2、1︰1、2︰1、4︰1、8︰1的情况下,相对应的细胞增殖抑制率分别为67.12%、47.18%、31.15%、27.61%、15.55%、15.95%;利用5,10,20,40,60,100 mg/L人脐带间充质干细胞条件培养基对Hela细胞进行培养,相对应的细胞增殖抑制率分别为0.61%、40.1%、63.47%、80.61%、93.56%、90.65%,说明人脐带间充质干细胞和条件培养基呈一定的浓度依赖性抑制Hela细胞的增殖。

Abstract:

BACKGROUND: Mesenchymal stem cells have the specific chemotaxis to the inflammation and tumor tissue, but the effect of mesenchymal stem cells on the growth of cervical cancer cells becomes an urgent problem.
OBJECTIVE: To investigate the effect of human umbilical cord mesenchymal stem cells on the proliferation of cervical cancer Hela cells.
METHODS: Hela cells were co-cultured with human umbilical cord mesenchymal stem cells at different number or its conditioned medium at different concentrations for 3 days. Then, cell counting kit-8 was used to detect the proliferation of Hela cells.
RESULTS AND CONCLUSION: When Hela cells were co-cultured with human umbilical cord mesenchymal stem cells at ratios of 1:3, 1:2, 1:1, 2:1, 4:1, 8:1, the relative proliferation inhibition rates were 67.12%, 47.18%, 31.15%, 27.61%, 15.55% and 15.95%, respectively. When the Hela cells were co-cultured with human umbilical cord mesenchymal stem cell conditioned medium at 5, 10, 20, 40, 60, 100 mg/L, the relative proliferation inhibition rates were 0.61%, 40.1%, 63.47%, 80.61%, 93.56%, 90.65%, respectively. These findings indicate that the proliferation of Hela cells can be inhibited by co-culture with human umbilical cord mesenchymal stem cells at a certain concentration-dependent manner.
