The sensitive red fluorescence dye BODIPY® 665/676, and embedding in the water-soluble resin Technovit® 7100 were used to demonstrate free fatty acids in the epidermis of seven semi-aquatic and aquatic mammalian species with a sparse or dense hair coat. The staining generally marked lipid layers of varying thickness between the lamellae of the Stratum corneum, as found particularly in very densely haired species (otter), but also in rather sparsely haired animals (beaver, nutria), and especially in the seal. The very sparsely haired capybara contained no free fatty acids in the corneal layer system, but exhibited an accumulation of such substances in the vital epidermis. All haired species showed a strongly positive reaction staining of the sebaceous glands. In the hairless species, a distinct intracellular staining was restricted to cells of the thick vital epidermis in the hippopotamus, whereby in the Str. corneum positive intercellular reactions appeared. In the dolphin, on the contrary, positive intercellular reactions became visible in the vital epidermis, whereas in the Str. corneum the lipids concentrated in large longitudinal intracellular vesicles. |
