this was demonstrated in several differentiating systems : in 3t3 preadipocytes which change their shape from a fibroblastic to a spherical shape when stimulated to differentiate with adipogenic medium , we observed a decrease in mrna levels and in the synthesis of fibronectin , beta-integrin , and the microfilament proteins , vinculin , alpha-actinin , tropomyosin and actin .
