Figure 5

(a) Photomicrograph of histological section Nile tilapia leather illustrating the superficial dermis containing blood vessels (vs) and deep dermis formed by overlapping layers of parallel and longitudinal collagen fibers (fp). In the hypodermal layer, the presence of melanophores (me) is observed. Staining: Masson’s trichrome. Objective lens: 20x; (b) scanning electron micrograph of the superficial dermis (ds) and deep dermis (dp), in which the overlapping layers of parallel collagen fibers interspersed by the transverse fibers (fct) are observed. Magnitude: 200x. Bar: 100 μm; (c) scanning electron micrograph showing the interweaving of the collagen fibers (fc) of the superficial dermis. Magnitude: 350x. Bar: 50 μm.
