the formation of granulation tissue, reepithelialisation, and neovascularisation and lasts from day four until day 14.Granulation tissue formation occurs 3–5 days after injury and overlaps with the preceding inflammatory phase.Stage 4: Formation of granulation tissue.It has been shown that myofibroblast apoptosis occurs when the wound closes and the tissue recovers, at least in part, its tensile strength, suggesting that . We speculate that this may be a .This granulation tissue acts as a scaffold for the migration and differentiation of wound cells, supporting both the formation of new blood vessels and . Thus, organized formation of granulation tissue following PVI treatment may be attributed to the increased growth of new vessels .

Wound healing: cellular mechanisms and pathological outcomes
Granulation tissue formation constitutes a key step during wound healing of the skin and other organs. These cells have osteogenic potential and, together with the newly formed blood vessels, contribute to the granulation of tissue .Re-formation of the hierarchically organized mineral bone tissue occurs over various phases: an initial ‘wave’ is characterized by the formation of a fibrous network of collagen in which .
Occurs when initial injury cannot be repaired solely by cell regeneration; Cells that cannot be regenerated (e. Granulation tissue concomitantly initiates regenerative M2 macrophages polarization, fibroblast proliferation, myofibroblast differentiation with subsequent contraction of the wound, new vessel formation, and matrix deposition. mucocele, traumatized hemangioma, pyogenic granuloma.Granulation tissue is reddish connective tissue that forms on the surface of a wound when the wound is healing.
