Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells are the ideal cells for tissue repair. Whether the ability of in vitro proliferation can be enhanced is a key factor to promote tissue repair.
OBJECTIVE: To observe the effect of transforming growth factor β1 on the proliferation of bone marrow mesenchymal stem cells in vitro.
METHODS: Blood samples were taken from the central artery of rabbits to prepare platelet-rich fibrin by centrifugation method which was then placed into fresh DMEM at 37 ℃ for 7, 14, 21, 28 days to collect exudates. The mass concentrations of transforming growth factor-β1 in the exudates of platelet-rich fibrin were detected. Rabbit bone marrow mesenchymal stem cells were collected and cultured in the conditioned medium made by the exudates of platelet-rich fibrin, and the proliferation of cells was observed.
RESULTS AND CONCLUSION: Concentration of transforming growth factor β1 was increased with time increasing, increased fastest at 21-28 days, and peaked at 28 days. Under the same stimulus concentration, the proliferation of bone marrow mesenchymal stem cells was reduced at 0-1 day, increased obviously at 1-2 days, and entered into a steady phase at 2-3 days. Under 150 ng/L transforming growth factor β1, bone marrow  mesenchymal stem cells proliferated fastest. Experimental findings indicate that with the increase of time, the concentration of transforming growth factor β1 in the exudates of platelet-rich fibrin increase gradually, and the conditioned media containing different concentrations of transforming growth factor β1 play different roles in promoting the proliferation of bone marrow mesenchymal stem cells. Bone marrow mesenchymal stem cells cultured in the conditioned medium containing 150 ng/L transforming growth factor β1 for 2-3 days can proliferate fastest.
