Abstract
ObjectivesTo study the effect of platelet-derived growth factor (PDGF) and fluid shear stress (FSS) on cell proliferation and c-fos expression in osteoblasts.
MethodsDifferent concerntrations of PDGF (0, 10, 30, 50 ng/ml) were used to stimulate primary cultured osteoblasts, respectively. CCK-8 and real-time quantitative PCR were performed to detect cell proliferation and c-fos mRNA expression. Furthermore, osteoblasts were stimulated by PDGF and loaded by FSS of 12 dyne/cm2 for 1 h, together. CCK-8, real-time quantitative PCR and western blot were performed to detect cell proliferation, c-fos mRNA and protein expression, respectively.
ResultsPDGF or FSS can respectively increase cell proliferation (FFSS = 6.500, PFSS< 0.05; FPDGF = 6.077, PPDGF< 0.05) and the expression levels of c-fos mRNA in osteoblasts (FFSS = 6.425, PFSS< 0.05; FPDGF = 7.549, PPDGF< 0.05) . There was no synergistic effect between PDGF and FSS (Fproliferation = 1.826, Pproliferation> 0.05; Fc-fos mRNA = 2.101, Pc-fos mRNA> 0.05; Fc-fos protein = 1.561, Pc-fos protein> 0.05) .
ConclusionPDGF itself or combined with FSS can increase cell proliferation and c-fos expression levels in osteoblasts, but there is no synergistic effect between PDGF and FSS on cell proliferation and c-fos expression in osteoblasts.
