Definition of scale in the semi-quantitative evaluation of the histological sections.

Scale	Epithelization	PMNL	Fibroblasts	Luminized vessels
0	Thickness of cut edges	Absent	Absent	Absent
1	Migration of cells (<50%)	Mild ST	Mild ST	Mild SCT
2	Migration of cells (≥50%)	Mild DL/GT	Mild GT	Mild GT
3	Bridging the excision	Moderate DL/GT	Moderate GT	Moderate GT
4	Keratinization	Marked DL/GT	Marked GT	Marked GT

ST, surrounding tissue; DL, demarcation line; SCT, subcutaneous tissue; GT, granulation tissue. PMNL, polymorphonuclear leukocytes.
