Abstract:

 BACKGROUND: The metastatic potential of hepatocellular carcinoma cells is key factor influencing patient’s prognosis. To observe the effect of human bone marrow mesenchymal stem cells on metastasis of hepatocellular carcinoma is of great significance for improving the lifetime of hepatocellular carcinoma patients.

OBJECTIVE: To explore the biological effect of human bone marrow mesenchymal stem cells on hepatocellular carcinoma cells with different metastatic potentials.
METHODS: Human bone marrow mesenchymal stem cells and hepatocellular carcinoma cell suspension with high and low metastatic potentials were respectively injected into the Transwell chamber, and after 36 hours of co-culture, ELISA method was used to detect the absorbance value as well as cell counting method was used to observe the changes in the invasion ability of hepatocellular carcinoma cells. The effects of human bone marrow mesenchymal stem cells on the proliferation of hepatocellular carcinoma cell suspension with high and low metastatic potentials were determined using cell counting kit-8. PCR method was adopted to measure the expression of osteopontin, bone specific sialoproteins, integration (alpha V), transforming growth factor beta 1 and programmed cell death protein 5.
RESULTS AND CONCLUSION: (1) The number of migrated hepatocellular carcinoma cells was significantly lower in the co-culture group than the single culture group, and based on the semi-quantitative detection of invasion ability, the absorbance value of the co-culture group was significantly lower than that in the single culture group (P < 0.05). (2) The expression of osteopontin and bone specific sialoproteins was significantly decreased in the co-culture group with high metastatic potential (P < 0.05), but there was no change in the expression of integration (alpha V) (P > 0.05). In the co-culture group with low metastatic potential, the expression of osteopontin, bone specific sialoproteins, and integration (alpha V) were declined remarkably (P < 0.05). (3) Results from the semi-quantitative detection of proliferation ability showed that the absorbance value of the co-culture group was significantly higher than that of the single culture group(P < 0.05). (4) In the co-culture group with high metastatic potential, the expression of transforming growth factor beta 1 was up-regulated significantly (P < 0.05), but the expression of programmed cell death protein 5 showed no changes(P > 0.05). However, in the co-culture group with low metastatic potential, the expression of transforming growth factor beta 1 and programmed cell death protein 5 was both increased dramatically (P < 0.05). These findings suggest that the human bone marrow mesenchymal stem cells reduce the invasion ability of hepatocellular carcinoma cells, and enhance their ability of proliferation.
