Fig. 2. Deletion of Stat3 in pre-osteoblasts induced skeletal deformities.

Fig. 2

a Illustration of Stat3 deletion in Osx-expressing pre-osteoblasts. b Western blotting of STAT3 in BMSCs from 4-week-old male Stat3fl/fl and OsxCre;Stat3fl/fl mice cultured in osteogenic medium for 7 days. The experiment was performed twice to similar results. c Representative views of 8-week-old male OsxCre and OsxCre;Stat3fl/fl mice. df Skeletal preparations from male OsxCre and OsxCre;Stat3fl/fl newborns were double-stained with alcian blue and alizarin red S. Arrows indicate calvarial lesions. g Microcomputed tomography (micro-CT) images of skulls from 4-week-old male OsxCre and OsxCre;Stat3fl/fl mice. Arrows indicate calvarial lesions. h Micro-CT images of distal femurs from 4-week-old male OsxCre and OsxCre;Stat3fl/fl mice. im Quantitative parameters of micro-CT, including bone volume per tissue volume (BV/TV), trabecular thickness (Tb.Th.), trabecular number (Tb.N.), trabecular space (Tb.Sp.), and cortical thickness (Ct.Th). n = 7. Two-tailed Student’s t test. Data represent the mean ± s.d. Source data are provided in the Source data file.
