Western blot analysis of Wnt signaling pathway components.

<p>(A) Western blotting of β-catenin, p-β-catenin, GSK3β, p-GSK3β, cyclin D1, c-myc and Runx2. One representative image from three independently conducted assays is shown. (B) Protein levels of β-catenin, p-β-catenin, GSK3β, p-GSK3β, cyclin D1, c-myc and Runx2 quantified by densitometry (n = 3, *p<0.05, **p<0.01 versus normal BMSCs).
