Evaluation of Human Amniotic Membrane as a Wound Dressing for Split-Thickness Skin-Graft Donor Sites

Table 3

Proliferation indices in samples of split-thickness skin-graft donor sites treated with human amniotic membrane or polyurethane foil on postoperative days 7 and 60 (evaluated by immunohistochemical staining with Ki-67 antibody).

Wound dressing material	Mean value ± standard error of the mean
	of proliferation index
	The 7th postoperative day	The 60th postoperative day
Human amniotic membrane	0.13 ± 0.0023	0.20 ± 0.0051
Polyurethane foil	0.15 ± 0.014	0.29 ± 0.0069
