Objective To observe the effect of Zhuanggu Zhitong Recipe (ZGZTR) on Wnt/β-catenin signaling pathway of osteoblast cultured in vitro . Methods Osteoblasts from neonatal SD rats were cultured in primary culture then divided into 4 groups randomly, sham-operated group, model group, control group and Chinese medicine (CM) group. Osteoblasts were identified after 3 generations, then intervened by drug containing serum for 48 h. The mRNA and protein expression of Wnt3a, β-catenin,LRP5, GSK3β were detected. Results Compared with sham-operated gro...
