Characterization of Dental Pulp Myofibroblasts in Rat Molars after Pulpotomy

Myofibroblasts express alpha smooth muscle actin (α-SMA) and play a critical role in wound healing. Myofibroblast differentiation is controlled by the joint actions of transforming growth factor beta 1 (TGF-β1) and the extradomain A fibronectin splice variant (EDA-FN). Currently, the contribution of myofibroblasts to dental pulp healing is unknown. Therefore, we analyzed expressional characteristics of α-SMA–positive cells and investigated TGF-β1, EDA-FN, and α-SMA expression levels after pulpotomy to better understand dental pulp healing.
