WebEpithelialization occurs when the epidermis regenerates over a wound surface. Basal keratinocytes travel from the wound edges, where they multiply until they meet in the middle. The basal lamina is a scaffolding secreted by the epithelial cells as they travel outwards from the wound edges. Does granulation come before epithelialization? WebJan 28, 2024 · Hypergranulation is excessive granulation that rises above the wound surface, imposing a barrier to the inward-migrating epidermis. Certain areas — such as the scalp, temples, and lower leg — are prone to forming hypergranulation tissue. nottingham city elections
