Resumen
Myofibroblastic differentiation is an important event
in gingival wound healing and chronic inflammation. Transforming frowth factorb
1 (TGF-b1) is a potent growth factor that has been implicated in this process.
Gingival myofibroblasts have an increased ability to remodel the extracellular
matrix and this feature has been associated with changes in the distribution of
F-actin and the expression of the myofibroblast marker a-smooth muscle actin.
In the present study we have analyzed the role of TGF-b1 and the signaling routes
activated by this factor in the cytoskeletal changes that characterize the myofibroblastic
differentiation process in human gingival fibroblasts.
