Abstract

The present work was aimed to study the piglet skin by light and transmission electron microscopy. This investigation has considered six samples of the abdominal skin of six male two-month-old piglets, which were collected from the El-Amria abattoir, Alexandria governorate, Egypt. The skin constitutes three layers: the epidermis, dermis, and hypodermis. Some hair follicles appeared among epidermal cells. Melanin granules appeared scattered among the basal cells; in addition the granular layer was discrete and comprised of one layer of flattened keratinocytes. This paper presents a novel record by transmission electron microscopy (TEM) for the presence of the Merkel cells that were observed with neuroendocrine granules and different densities in the two-month-old male piglet. In addition, Langerhans-like cells appeared in between the keratinocytes of the stratum spinosum cells. The Langerhans-like cells had lucent cytoplasm with Birbeck granules (tennis-racket shape) around the nucleus, melanin granules. Also, there were numerous tonofilaments and Merkel cells in the keratinocytes of the stratum spinosum. Measurements for the epidermis and dermis thickness were 49.6±6 and 1005 ±19 µm. Our study concluded that pigskin is applicable, reliable animal model for human skin.
