The electron microscopic study was conducted on skin by using two male and two female adult Zovawk pig. The stratum basale consisted mainly of a single layer of cuboidal to low columnar cells which had large ovoid nuclei with numerous indentations, cytoplasmic melanin granules, and many tonofilaments. The stratum basale were also added by some suprabasal cells which might contribute to proliferation. A stratum spinosum rested upon the proliferating stratum basale and consisted of a layer of irregular–shaped keratinocytes two to four cells deep which were increasingly flattened in the outermost layers. These cells had large spherical nuclei with sparse chromatin, electron lucent cytoplasm containing small mitochondria. A stratum granulosum layers also contained irregularly shaped, non-membrane-bounded, electron dense keratohylin granules. A stratum corneum layer appeared clear cytoplasmic organelles without nuclei. The dermis consisted of dense irregular connective tissue with a felt work of collagen, reticular and elastic fibers embedded in an amorphous ground substance. The fine structure of the cuboidal secretory cells comprised of coiled, deep fundic zone of the apocrine glands. The nuclei of these cells were basally situated and sometimes cleft and were in close proximity to small mitochondria with densely packed cristae. Most of the cytoplasm was filled with closely packed, electron lucent, spherical or ovoid secretory granules.
