Italian term (edited): riepitelizzazione a nappo

wound healing/ reepithelialization

Healing by second intention occurs when there is tissue loss, as in extensive burns and deep ulcers. The healing process is more prolonged than in healing by primary intention because large amounts of dead tissue must be removed and replaced with viable cells. A, Open area is more extensive; inflammatory reaction is more widespread and tends to become chronic. B, Healing may occur under a scab formed of dried exudate, or dried plasma proteins and dead cells (eschar). C, Fibroblasts and **capillary buds** migrate toward center of would to form granulation tissue, which becomes a translucent red color as capillary network develops. Granulation tissue is fragile and bleeds easily. D, As granulation tissue matures, marginal epithelial cells migrate and proliferate over connective tissue base to form a scar. Contraction of skin around scar is the result of movement of epithelial cells toward center of wound in an attempt to close the defect. Surrounding skin moves toward center of wound in an effort to close the defect.

In healing by first intention (primary union), restoration of tissue continuity occurs directly, without granulation; in healing by second intention (secondary union), wound repair following tissue loss (as in ulceration) is accomplished by closure of the wound with granulation tissue. This tissue is formed by proliferation of fibroblasts and extensive capillary budding at the outer edges and base of the wound cavity, with slow extension from the base and sides of the wound toward its center. If, however, the wound is very deep and extensive, granulation tissue cannot fill the defect and grafting may be needed to cover the space and avoid severe contracture and loss of function. healing by third intention (delayed primary closure) occurs when a wound is initially too contaminated to close and is closed surgically 4 or 5 days after the injury. (See also illustrations at healing.)

Endothelial cell migration

VEGF induces endothelial cell migration in wound healing through two primary mechanisms, chemotaxis and vasodilatation. In the initial phase of angiogenesis, endothelial cells migrate before mitotic division 18. *Capillary budding* may also be sustained for up to 4 or 5 days by endothelial elongation and migration without proliferation. How VEGF stimulates endothelial cell migration is detailed below.
