Healing Score

0	healed	fibrocytes and collagen, multinucleated giant cells; capillaries; dense cellular connective tissue (dominant)
1	midstage healing to healed	capillaries; multinucleated giant cells; islands of loose matrix and dense collagen
2	midstage healing	macrophages (hemosiderin laden, cellular and substrate debris), fibroblasts, lymphocytes and admixture substrate (collagen and isolated fibrin fragments), multinucleated giant cells; admixture of neovascular buds and capillaries (dominant); loose cellular connective tissue
3	early to midstage healing	neovascular buds and capillaries; multinucleated giant cells; admixture of loose collagen (dominant) and fibrin
4	early stage healing	macrophages (erythrophagocytosis, cellular and substrate debris phagocytosis), fibroblasts, neutrophils, eosinophils, lymphocytes, multinucleated giant cells, plasma cells; neovascular buds; granulation tissue; admixture of fibrin and loose collagen
5	residual blood to early stage healing	neovascular buds; admixture of fibrin (dominant) and loose collagen
6	residual blood	cells and fibrin/protein; no vasculature; fibrin, no collagen
