Criteria to evaluate histological scores of wound healing for H&E staining.

Score	Criteria
1–3	None to minimal cell accumulation. No granulation tissue or epithelial travel.
4–6	Thin, immature granulation tissue that is dominated by inflammatory cells but has few fibroblasts, capillaries, or collagen deposition. Minimal epithelial migration.
7–9	Moderately thick granulation tissue can range from being dominated by inflammatory cells to more fibroblasts and collagen deposition. Extensive neovascularization. Epithelium can range from minimal to moderate migration.
9–12	Thick, vascular granulation tissue dominated by fibroblasts and extensive collagen deposition. Epithelium partially to completely covering the wound.
