Detailed explanation-1: -Granulation tissue is produced during the repair phase. This is a complex of fibroblasts, vascular endothelial cells, and macrophages within a matrix of collagen and fibrin. Fibroblasts and capillaries appear in the wound by day 3. Fibroblasts use the fibrin clot as a matrix and replace it with new matrix.
Detailed explanation-2: -During wound healing, granulation tissue usually appears during the proliferative phase. Angiogenesis is the process by which new blood vessels form, bringing in tiny capilarry buds that appear as granular tissue. Granulation tissue sets the stage for epithelial tissue to be laid down on top of the wound bed.
Detailed explanation-3: -The proliferative phase is characterized by the formation of granulation tissue, reepithelialization, and neovascularization. This phase can last several weeks.
