The role of the fibronectin synergy site in skin wound healing

Upon skin barrier disruption, complex cellular and molecular events are activated to repair the damage and restore skin integrity. In adulthood, the outcome of this process can result in scarring and fibrosis, whereas complete tissue regeneration is observed in fetal wounds and wounds in lower vertebrates and invertebrates .Although there is abundant literature about the factors and mechanisms that determine the endpoint of either scarring/fibrosis or regeneration after tissue injury, the process is still poorly understood. After cutaneous injury, fibronectin (FN) is instantly released and deposited by cells, and represents a major ECM component in all stages of the wound healing process. F…
