Conductivity of intact epithelium, G_intac, apart from apoptosis or edge damage, was measured in the conductance scanning set-up before inflicting a lesion. The decrease in g_leak, associated with a single-cell lesion, between 2 and 8 min post lesion was determined. n, number of leaks; m, number of monolayers. Wilcoxon-Mann-Whitney U test with Bonferroni's correction for multiple testing
