Epithelialization & Tissue Hydration

"Epithelialization" refers to the process by which epithelial cells (primarily keratinocytes in skin) migrate, proliferate, and differentiate to restore the barrier after injury, a critical phase in wound healing that requires a moist environment to function efficiently[1][2][3][7]. "Tissue hydration" is the maintenance of the appropriate water content in tissues—especially the stratum corneum of the skin—via structural lipids and the tight packing of corneocytes; hydration is essential for cell viability, migration, and proper wound closure[1][7]. These are interconnected physiologic processes and not individual molecules or druggable targets, though they are influenced by cellular pathways, growth factors, and topical therapies. If you need information about specific molecular targets that regulate or affect epithelialization and tissue hydration (such as epidermal growth factor receptor, aquaporins, filaggrin, or other skin barrier proteins), please specify.
