Table 1 Histological scoring parameter of epithelialization, angiogenesis, granulation tissue formation, and inflammatory cells

From: Characterization of burn wound healing gel prepared from human amniotic membrane and Aloe vera extract

Parameter/Score 0 1 2 3
Inflammatory cells 1–5 inflammatory cells per histological field 5–8 inflammatory cells per histological field 8–11 inflammatory cells per histological field 11–15 inflammatory cells per histological field
Epithelialization Absence of epithelial proliferation in ≥70% of tissue Incomplete epidermal organization in ≥50% of tissue Moderate epithelial proliferation in ≥60% of tissue Complete epidermal remodeling in ≥80% of tissue
Angiogenesis Absence of angiogenesis including congestion and hemorrhage 2–4 vessel per site, congestion and hemorrhage 4–6 vessel per site, slight congestion 7–8 vessel per site vertically disposed towards the epithelial surface
Granulation Tissue None, completely disorganized and distorted Minimal/immature thin Mild/moderately mature granule layer Evident/ Thick, ≥80% organized
