Mouse skin histology.

Hemotoxylin and eosin staining of normal mouse skin showing cutaneous compartments and structures. The basal epidermis (BE) consists of a single layer of proliferating keratinocytes, which give rise to the differentiating keratinocytes of the suprabasal epidermis (SBE). The latter ultimately form the stratum corneum (SC), the outermost barrier of the skin. The dermis (D) underlies the epidermis and houses several structures, including blood vessels (BV) and hair follicles (HF).
