Abstract:

BACKGROUND: Docetaxel, a cell cycle specific anti-tumor drug, is a drug that is used primarily for treating breast cancer; however, its efficacy is low when used for treatment of cancer not sensitive to radiotherapy. Bone marrow mesenchymal stem cells have been shown to strengthen the effects of tumor-specific targeting chemotherapy drugs.
OBJECTIVE: To investigate the effects of docetaxel combined with bone marrow mesenchymal stem cells (BMSCs) on human hepatoma cell line SMMC-7721.
METHODS: BMSC cells were cultured in vitro. The logarithmic growth of SMMC-7721 hepatoma cells were randomly divided into blank control group, BMSCs group and combined treatment group (combined treatment of BMSCs and docetaxel). SMMC-7721 cell cycle was detected using flow cytometry. Cell growth rate of SMMC-7721 was determined by MTT assay. mRNA and protein expressions of tumor suppressor genes PTEN and p53 were detected by reverse transcription polymerase chain reaction and western blot assay.
RESULTS AND CONCLUSION: Combined treatment of docetaxel and BMSCs inhibited SMMC-7721 cell proliferation. Compared with the blank control group, the number of cells at the G0/G1 phase was significantly increased in BMSCs group and combined treatment group. The cell growth rate of SMMC-7721 was significantly inhibited in BMSCs group compared with the blank control group, and that was further inhibited in combined treatment group (P < 0.05). mRNA and protein expression of PTEN and p53 were significantly increased in combined treatment group compared with BMSCs group and blank control group (P < 0.05). Our results suggest that BMSCs inhibit the growth of SMMC-7721 cells, and combined use of docetaxel and BMSCs strengthens the antitumor effect of BMSCs.
