Numbers of caspase-3+ cells in wounded human ex vivo tissue upon wound gel treatment. Shown is the number of caspase-3+ cells in treated skin biopsies counted within 4 fields of view (FOV) per biopsy (tape-stripped (TS), untreated control and treated with Oct, Pro, Lav, Bet, Act, Mic or Ver) of six donors. FOVs are assessed as technical replicates and data is presented as a mean ± standard deviation. Two-way analysis of variance (ANOVA) was performed using GraphPad Prism 9.3.1. ***p ≤ 0.001, ****p ≤ 0.0001.
