WebMigration of neighboring cells into the injury is important for rapid repair of damaged airway epithelium. We previously reported that activation of the A(2A )receptors (A(2A)ARs) mediates adenosine-stimulated epithelial wound healing, suggesting a role for adenosine in migration. Because A(2A)AR in … WebEpithelium, endothelium and mesothelium are three types of epithelial cell layers that line your internal organs, body cavities and form the outer layer of your skin. Epithelium generally lines pathways that are open to the external environment, such as your respiratory tract and digestive system.
