Abstract

Objective: To study the effects of Shenggu injection (SGI) on mRNA expression of vascular endothelia growth factor (VEGF) in rat osteoblastsin vitro and to explore its possible molecular mechanisms in promoting fracture healing.Methods: Rat osteoblasts culturedin vitro were stimulated with SGI according to the protocol. The expression levels of VEGF mRNA in the cells in every group were examined by reverse-transcriptase ploymerase chain reaction (RT-PCR).Results: When osteoblasts were stimulated with different concentrations of SGI for 5 days, the expression of VEGF mRNA peaked with 1 mg/ml SGI on the 5th day. When treated with 1 mg/ml SGI from the 1st to the 5th day, the expression of VEGF mRNA increased gradually with the increase of culturing time.Conclusion: SGI could promote significantly the expression of VEGF mRNA in rat osteoblastsin vitro. The levels of expression of VEGF mRNA changed along with different concentrations and stimulating time of SGI.
