A The expression of AKT1 and Twist1 in periosteal tissues determined by western blot analysis. B IHC staining analysis of STRO-1 protein in periosteal tissues (scale bar = 25 μm) and the quantitative analysis. C Periosteum calcified nodule staining (scale bar = 50 μm). D ALP activity in periosteal tissues. E OCN content in periosteal tissues. *p < 0.05 compared with rats receiving the Masquelet-induced membrane technique treated with inhibitor-NC, #p < 0.05 compared with rats receiving the Masquelet-induced membrane technique treated with miR-149-inhibitor + vector. Data were expressed as mean ± standard deviation. Comparison among multiple groups was conducted by one-way ANOVA, followed by Tukey’s post hoc test. MI the Masquelet-induced membrane technique, NC negative control, IHC immunohistochemistry, STRO-1 stromal cell antigen 1, ALP alkaline phosphatase, OCN osteocalcin, ANOVA one-way analysis of variance.
