Abstract：BACKGROUND:Basic fibroblast growth factor is a pluripotent cytokine that can promote the proliferation of mesodermal and neuroectodermal cells. <br> OBJECTIVE:To observe the effect of basic fibroblast growth factor in human periodontal ligament cells cultured in vitro. <br> METHODS:Human periodontal ligament cells at passage 5 were inoculated into the 96-wel plates at the density of 1×108/L, and were randomly divided into four groups. The cells were cultured inα-MEM containing 15%fetal bovine serum and 0, 1, 10, 100μg/L basic fibroblast growth factor, respectively. At 1, 3, 5, 7 days of the culture, the cellproliferation was determined, and the activity of alkaline phosphates was detected at 1 and 7 days. <br> RESULTS AND CONCLUSION:There were significant differences in the proliferation of human periodontal ligament cells among the four groups (F=6.586, P=0.024). As the increase of the basic fibroblast growth factor concentrations, the absorbance value was gradual y increased and reached the peak in 100μg/L basic fibroblast growth factor group (P<0.05). The alkaline phosphatase activity in basic fibroblast growth factor groups was lower than that of the control group (P=0.000), the higher the concentration was, the lower activity was (P<0.05). Results show that basic fibroblast growth factor can promote the proliferation of human periodontal ligament cells and inhibit the activity of alkaline phosphatase, and the effect is concentration-dependent.
