流动剪切力作用下原代大鼠成骨样细胞PGE2的表达
Effects of Fluid Shear Stress on PGE2 Synthesis of Primary Osteoblast-like Cells in Rats
摘要
Abstract
Objective:The purpose of this study is to study the function of PGE2 during the signal transduction in which fluid shear stress regulates the proliferation and differentiation of osteoblast_like cells.Methods: The isolated rat primary osteoblast_like cells were exposed to fluid shear stress 0.12 mN/cm2 for 5, 10, 15, 30, 60 and 120 minutes respectively in a flow chamber. The release of PGE2 was examined. Results: After exposure to fluid shear stress, the PGE2 synthesis of rat primary osteoblast-like cells increased significantly (P<0.01) when compared with the control. After 10 minutes, the release of PGE2 began to increase significantly (P<0.01) and the effect was maximal after 60 minutes (P<0.01).Conclusion: PGE2 pathway may be one of the signal_transduction pathways which can transduce the fluid shear stress into osteoblast_like cells and then stimulate the bone remodeling.关键词
