Abstract:
This paper was aimed to investigate the effect of Aralia echinocaulis containing serum on expression of β-catenin, Wnt-1, Frizzed-2, TCF and Axin in Wnt/β-catenin signaling pathway of primary osteoblasts. SD healthy female rats (n=80) were used to make A. echinocaulis containing serum by gastric perfusion for seven days with distilled water, A. echinocaulis decoction high dosage, middle dosage, and low dosage. In vitro, primary osteoblasts were cultured and identified. The third generation primary osteoblasts were taken and cultured for 48 h, then cells were treated with the different drug serums for 10 days and calcified nodules were counted by alizarin red staining. The cells were collected after treatment for 48 h and the expression levels of β-catenin, Wnt-1, Frizzled-2, TCF and Axin were detected by Real-time PCR and Western blot. The results suggested that the in vitro cells were primary osteoblasts; and after treatment, various doses groups could promote the mineralization ability of primary osteoblasts, up-regulate the mRNA and protein expression levels of β-catenin, Wnt-1, Frizzled-2, and TCF, and down-regulate the mRNA and protein expression levels of Axin. These findings indicated that A. echinocaulis containing serum can enhance the differentiation and proliferation of osteoblasts by regulating the expression levels of β-catenin, Wnt-1, Frizzled-2, TCF and Axin in Wnt/β-catenin signaling pathway of primary osteoblasts.
