Western blot of β-catenin, P-p38MAPK and P-Erk1/2 expression in Sox2-expressing cells and control cells cultured under osteogenic differentiation medium. a The phosphorylation level of p38MAPK in Sox2-expressing cells was down-regulated only at a later stage. p-Erk1/2 was not influenced between the two groups at different time points. b β-catenin expression was down-regulated in the whole process in Sox2-expressing cells
