Angiogenesis stimulation via endothelial cell and keratinocyte activation

Angiogenesis stimulation via endothelial cell/keratinocyte activation is not the name of a specific molecule or receptor but rather describes a complex biological process. Angiogenesis—the formation of new blood vessels—begins with the activation of endothelial cells, which respond to proangiogenic stimuli such as hypoxia, growth factors like vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) secreted by various cells including keratinocytes. Upon activation, these cells proliferate and migrate into surrounding tissues where they form new vessel structures. Keratinocytes also contribute by secreting cytokines and growth factors that modulate both inflammation and angiogenic signaling in skin pathologies such as psoriasis and during wound healing[3][4]. The molecular regulation involves multiple pathways including VEGF/VEGFR signaling for endothelial cells[3], EGFR/Erk5/Slug for keratinocyte migration[2], integrin-mediated adhesion/migration[1], Notch signaling for vessel patterning, and others. Because this entry refers to an entire physiological mechanism rather than an individual therapeutic targetable entity—such as a receptor or enzyme—it is considered incorrect as a molecular target name, though it accurately describes an important therapeutic context. If you need structured information on actual molecular targets involved in this process—such as "Vascular endothelial growth factor receptor 2" (VEGFR2) or "Epidermal growth factor receptor" (EGFR)—please specify which component you are interested in.
