Immunohistochemical analysis for osteoporotic bone regeneration induced by different nwHA bioceramics. (A) Decalcified H&E staining showing position of the newly formed bone within the implanted nwHA bioceramics. (B) ATP2A2 and (C) FGF23 staining of histological sections for different groups and the enlarged images of the pore region inside bioceramics. (D) Quantitative analysis of osteoblasts per unit area and mean fluorescence intensity values of ATP2A2 and FGF23. All data are reported as mean ± standard error. ANOVA with Tukey's post hoc test *p < 0.05, **p < 0.01, ***p < 0.001.
