RESUMO
BACKGROUND:Mesenchymal stem cels have the specific chemotaxis to the inflammation and tumor tissue, but the effect of mesenchymal stem cels on the growth of cervical cancer cels becomes an urgent problem. OBJECTIVE:To investigate the effect of human umbilical cord mesenchymal stem cels on the proliferation of cervical cancer Hela cels. METHODS:Hela cels were co-cultured with human umbilical cord mesenchymal stem cels at different number or its conditioned medium at different concentrations for 3 days. Then, cel counting kit-8 was used to detect the proliferation of Hela cels. RESULTS AND CONCLUSION:When Hela cels were co-cultured with human umbilical cord mesenchymal stem cels 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 cels were co-cultured with human umbilical cord mesenchymal stem cel 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 cels can be inhibited by co-culture with human umbilical cord mesenchymal stem cels at a certain concentration-dependent manner.
