Epithelial cells play a crucial role in wound healing primarily by migrating to cover the wound surface. This process, known as epithelialization, is essential for restoring skin integrity after an injury. When a wound occurs, the epithelial cells adjacent to the wound edge begin to proliferate and migrate across the wound bed, eventually covering it and forming a new layer of skin. This migration is vital because it helps to protect the underlying tissues from infection and external elements while also restoring the barrier function of the skin.

While creating a barrier to prevent infection is an important aspect of their role, it is the migration of epithelial cells that directly addresses the need to cover the wound area and facilitate proper healing. Epithelial cells do not produce collagen; that is the role of fibroblasts, which contribute to the structural framework of the wound healing process. Additionally, while exudate may be produced in the wound healing process, it is not a primary function of epithelial cells themselves but rather a result of the inflammatory process and cellular activity in response to injury.
