Figure 1. No differences in keratinocyte turnover and skin homeostasis among inner and outer foreskin mucosa from sexually active men.

A) Fibronectin and D) keratin 6 concentrations in foreskin lysates from all subjects sexually active within the past 2 weeks (n = 17) were measured by MBA. B) Percent of Ki-67+ nuclei among all epithelial nuclei on sections from 9 participants. C) Representative staining for Ki67 and SYTOX orange (nuclei). E) Median epithelial thickness (µm) was computed measuring 3–5 H&E-stained sections of ∼26.5 mm² inner/outer foreskin for each participant (n = 17). F) Representative H&E staining G) Parakeratosis was quantitated from H&E sections from all subjects (n = 17). All p values are from FDR-adjusted Wilcoxon tests.
