Effect of the cell-free fat extract (CEFFE) on epidermal cell proliferation. a Proliferating cell nuclear antigen (PCNA) staining in expanded tissue. Arrows indicate PCNA-positive cells. More PCNA-positive cells are present in CEFFE-treated tissue. Scale bar: 200 μm. b Quantitative analysis of the PCNA-positive cell number. CEFFE treatment significantly increases epidermal cell proliferation. Data are expressed as means ± SD. p < 0 05
