Differential secretion of wound healing mediators. Secretion of HGF, CCL27, IL-6, CXCL8, CCL2 and VEGF was determined in n = 3 normal skin (Nskin) and n = 3 keloid scars (Kscar) skin equivalents, with or without monocytes (mono). The Kruskal–Wallis test with post hoc Dunn’s multiple comparisons test (HGF, CCL27, IL-6, CXCL8, VEGF) or an ordinary one-way ANOVA with post hoc Tukey’s multiple comparisons test (CCL2) was employed. Graphs show mean ± SEM, with *p < 0.05. SE skin equivalents, mo monocytes, N normal skin, Ks keloid scar
