The position of extracellular vesicles (EVs) during the proliferation phase of wound healing. (a) Neovascularization. The damage website is inside a state of hypoxia, hence inducing activation of endothelial cells (ECs) and recruitment of endothelial The damage site is in the state of hypoxia, thus inducing activation of endothelial cells (ECs) and recruitment of endotheprogenitor cells (EPCs), which encourage new vessel formation by two mechanisms–angiogenesis and vasculogenesis, lial progenitor cells (EPCs), which promote new vessel formation by two mechanisms–angiogenesis and vasculogenesis, respectively. (b) The wide range of EVs contributes to neovascularization. Synthesis of significant pro-angiogenic variables is respectively. (b) The range of EVs contributes to neovascularization. Synthesis of critical pro-angiogenic elements is propromoted by EVs derived from saliva, macrophages, EPCs, and osteoblasts. They stimulate ECs migration, proliferation, moted by EVs derived from saliva, macrophages, EPCs, and osteoblasts. They stimulate ECs migration, proliferation, and and vascular tube formation by transferring diverse cargos (mRNA, miRNA, MMPs). Re-epithelialization.
