Histological parameters and semi-quantitative scoring system for day 2 wounds

Scale	Epithelialization	PMNL a	MM b	Fibroblasts	Endothelial cell activity
0	No proliferation at wound edge	No or very few cells present	No or very few cells present	No or very few plump fibroblasts present	No vessels with plump endothelial cells
1	Hyperplasia/hypertrophy at wound edge	Few cells or focal pattern, ≤40% of total cellularity	≤20% of total cellularity	≥50% spindle cells, ≤50% plump fibroblasts	≤50% vessels with plump endothelial cells
2	Migration of cells over wound bed	Numerous cells present in all layers, ≥40% of total cellularity	≥20% of total cellularity	≥50% plump fibroblasts, ≤50% spindle cells	≥50% vessels with plump endothelial cells
