Any process that activates or increases the rate or extent of epithelial cell proliferation, contributing to the restoration of integrity to a damaged tissue following an injury. [GOC:dph]
Positive regulation of epithelial cell proliferation is a crucial process in wound healing. It involves a complex interplay of signaling pathways and cellular responses, orchestrating the repair and regeneration of damaged epithelial tissues. The process begins with the detection of injury, triggering the release of growth factors and cytokines that promote cell survival, migration, and proliferation. These signaling molecules bind to their specific receptors on the surface of epithelial cells, activating downstream signaling cascades. The activation of key transcription factors like AP-1 and NF-κB leads to the expression of genes involved in cell cycle progression, proliferation, and migration.
Injured epithelial cells, often located at the wound edge, undergo a process called epithelial-mesenchymal transition (EMT), where they lose their epithelial characteristics and acquire mesenchymal features. This allows them to migrate into the wound space and contribute to the closure of the wound. During this process, the cells also exhibit increased motility and proliferation, driven by the activation of signaling pathways like the MAPK and PI3K pathways.
As the wound heals, the proliferating epithelial cells gradually differentiate and form a new epithelial layer, restoring the integrity of the damaged tissue. This process involves the expression of genes involved in cell-cell adhesion, tight junction formation, and differentiation. The newly formed epithelial layer acts as a barrier against infection and environmental insults, protecting the underlying tissues.
The regulation of epithelial cell proliferation in wound healing is a highly dynamic process influenced by a complex interplay of growth factors, cytokines, signaling pathways, and cellular responses. This intricate interplay ensures the coordinated and efficient repair of damaged epithelial tissues, restoring tissue function and integrity.'
