β‐catenin protein expression in callus tissue with or without intermittent parathyroid hormone treatment. (A) Representative hematoxylin and eosin stained histological samples from each treatment group. Fracture site is marked by a dashed black line. Western blot of (B) total β‐catenin; (C) hypophosphorylated (active) β‐catenin; and (D) hyperphosphorylated (inactive) β‐catenin. Corresponding quantification is graphed underneath each plot. Data are mean ± SEM are represented as the densitometric ratio of each experimental group relative to the saline‐treated animals. n = 5‐6, P < .05, Kruskal‐Wallis test. Groups not sharing a letter (eg a, b) are significant. Groups sharing a letter (eg a, a) are not significantly different
