Endochondral ossification is characterized by a significant interdependence between cell shape and cytoskeletal organization that accompanies the onset of chondrogenic signaling. However, the mechanisms mediating these interactions have not been well studied. Here, treatment with transforming growth factor (TGF)-beta3 at a later stage of chondrogenesis led to activation of Smad-2 signaling and the formation of intense stress fibers, which resulted in suppressing chondrogenic differentiation of leg bud mesenchymal cells. Moreover, specific siRNA knockdown of Smad-2 reduced TGF-beta3-induced stress fibers via physical interactions with beta-catenin. In conclusion, our results indicate that TGF-beta3-induced Smad signaling, in conjunction with beta-catenin, is involved in the reorganization of the actin cytoskeleton into a cortical pattern with a concomitant rounding of cells.
