Morphometric evaluation of sea bream skin during wound healing after scale removal. The thickness of the epidermis, basement membrane and dermis during sea bream skin recovery after scale removal is represented. Each value represents the mean ± SEM (N = 3). Statistical significance between groups was assessed using a two-way ANOVA followed by Fisher’s Least Significance Difference (LSD) post-test. Statistical significances were considered at p < 0.05 and differences in intact and regenerating skin during the experimental trial are annotated with different letters and comparisons between intact and regenerating skin at the same time point are signalled with an asterisk. A histological image of the skin layers at the start (0 h) and end (4 days after wounding, daw) of the experimental trial is represented beside each graph in order to illustrate the induced tissue aggression and the respective recovery with time. Ep: epidermis; bsl: basal layer; bsm: basement membrane; dm-l: loose dermis; dm-c: compact dermis; sc: scale; scp: scale pocket; mlc: melanocytes; blc: blood vessel; ext: exterior. Scale bars: 20 μm (scale bars alone) and 50 μm
