Osteoclastogenesis stimulated by OSM is enhanced in primary calvarial bone cell cultures from Wnt16−/- mice. Primary calvarial periosteal cells from wild-type (WT) and Wnt16−/- mice were stimulated with 100 ng/mL mOSM for 11 days. Cells were TRAP stained (A) and numbers of TRAP+MuOCL with more than 3 (B) and 10 nuclei (C) as well as the total surface (D) covered by TRAP+MuOCL were analyzed. Scale bars, 500 µm. Expression of Acp5 (E), Ctsk (F), Tnfs11 (G) and Tnfrs11b (H) after mOSM treatment for 11 days. Individual values are presented in all graphs with the mean shown as horizontal lines and ±SEM as vertical lines. ###P<0.001, ##P < 0.01 vs WT, Student’s t-test. ***P<0.001*P < 0.05 vs genotype specific untreated control, two-way ANOVA followed by Sidak’s multiple comparison test for the effect of mOSM treatment. §§§P<0.001, ns (not significant) P>0.05 for the effect by mOSM in WT vs the effect by mOSM in Wnt16−/- cells analyzed by interaction in two-way ANOVA.
