Fig. 3 (IMAGE) Osaka University Caption The in vivo role of activin A in osteoclastogenesis in an experimental mouse model of cholesteatoma. INHBA inhibition in fibroblasts reduced osteoclast formation on the parietal bone surface under the cholesteatoma mass. Red, osteoclasts; green, parietal bone surface. Scale bars: 500 µm.
