Features of angiogenesis in skin tissue regeneration

Restoration and regeneration of tissues are complex processes involving a large number of signaling mechanisms. In this study possible mechanisms of angiogenesis during tissue regeneration are presented. One of these mechanisms is the creation of a new capillary layer by angiogenesis. Previously it was believed that high and rapid levels of capillary growth are necessary for optimal healing of tissues. But several studies have demonstrated that a period of vascular regression occurs after the growth of blood vessels in a wound, and the number of the newly formed vessels decreases until the number of the blood vessels is equal to the density of the vascular network in the intact tissue. Reduced inflammation and angiogenesis are features of optimal healing.
