Detailed explanation-1: -Epithelialization is defined as a process of covering denuded epithelial surface. The cellular and molecular processes involved in initiation, maintenance, and completion of epithelialization are essential for successful wound closure.
Detailed explanation-2: -Epithelial wound healing involves coordinated migration and proliferation of epithelial cells. Epithelial cells adjacent to the wound migrate as a sheet to cover denuded surfaces, which is also referred to as “epithelial restitution”.
Detailed explanation-3: -Platelet-derived growth factors are released into the wound that cause the migration and division of cells during the proliferative phase.
Detailed explanation-4: -Epithelialisation is the formation of epithelium over a denuded surface. Epithelialisation of an incisional wound involves the migration of cells at the wound edges over a distance of less than 1 mm, from one side of the incision to the other. Incisional wounds are epithelialised within 24 to 48 h after injury.
