Signaling pathways involved in gastrointestinal epithelial restitution. In order to regain homeostasis after injury, gastrointestinal epithelial cells need to migrate and proliferate. Cells in the edges of wounds migrate to cover denuded surfaces while cells behind the migration front proliferate to accelerate this process.
