[The structure of the skin of the ear in domesticated pigs, with special reference to their use for human dermatological research. 2. Specific histology of the integument]. / Untersuchungen zur Struktur der Ohrhaut beim Hausschwein, unter besonderer Berücksichtigung einer Verwendung in der humandermatologischen Forschung: 2. Spezielle Histologie des Integuments.

Based on light microscopy, the study describes the specific histology of the ear integument of the white domesticated pig. After careful tissue fixation and embedding, routine histological staining, collagen fibre staining, fat demonstration based on frozen sections, and ink injection of the integumental blood vessel system were applied. A detailed description is presented of the structure of the skin layers (epidermis, dermis, hypodermis), the ear cartilage envelopes (fascia, perichondrium), the plica scaphae, the blood vessel distribution, the architecture of the collagen fibre bundles, as well as the hair follicles and the skin glands (sebaceous glands, apocrine tubular glands). The results are discussed with regard to a direct comparison with the histological structure of the human integument, and the advantages and disadvantages of the use of the porcine ear skin as model system in human dermatological research are emphasized.
