New insights into the roles of myofibroblasts and innervation during skin healing and innovative therapies to improve scar innervation

During the resolution phase of normal skin wound healing, there is a considerable loss of various cell types, including myofibroblasts by apoptosis. Inappropriate delay of apoptosis, and thus increased survival of myofibroblasts, may be a factor leading to pathologies and excessive scarring. Considerable data now clearly suggest that innervation plays a major role in wound healing, including the modulation of fibroblast cellular activity. An...
