This study was conducted on skin samples from New Zealand white rabbits during the period E15 days prenatal to E25. to investigate the histomorphological development of the skin, hair follicle, Sebaceous glands. Early in the fetal life (E15) the epidermis is in the form of simple squamous epithelium or stratified Nonkeratinized squamous epithelium of two or more layers, depending on the region studied, while the dermis is in the form of loose connective tissue composed of mesenchymal cells in a loose and irregular shape. (E20) prenatal, the epidermis is stratified squamous epithelium non-keratinized composed of more than three layers including the periderm, the intermediate layer and the basal layer in all regions, except Fingered hand and foot that appearance keratinized squamous. the cells of the mesoderm begin to condense under the basal layer, indicating the beginning of the formation of hairs placodes. Stratification became evident in(E25) of prenatal with a marked keratinized and extension of hair follicles in the dermis, accompanied by the beginning of the development of sebaceous glands in the form of a group of cells. During our study of the development of the skin of the New Zealand rabbit before birth, we could not notice any sweat glands in the examined skin samples. [ABSTRACT FROM AUTHOR]
