Histologic image showing a section of epidermis. Stratum basale labeled near bottom.

The stratum basale (basal layer, sometimes referred to as stratum germinativum) is the deepest layer of the five layers of the epidermis, which is the outer covering of skin in mammals.

The stratum basale is a continuous layer of cells. It is often described as one cell thick, though it may in fact be two to three cells thick in glabrous (hairless) skin and hyperproliferative epidermis (from a skin disease).^[1]

The stratum basale is primarily made up of basal keratinocyte cells, which can be considered the stem cells of the epidermis. They divide to form the keratinocytes of the stratum spinosum, which migrate superficially.^[2] Other types of cells found within the stratum basale are melanocytes (pigment-producing cells), Langerhans cells (immune cells), and Merkel cells (touch receptors).

Although busulfan, a bifunctional alkylating agent, is known to induce cataracts in infant rats, the full nature of busulfan-induced ocular lesions has not yet been shown. In order to clarify this point, 6-day-old rats were treated with a single dose of 20 mg/kg busulfan and the ocular tissue was hi

The hippocampus arises from the medial region of the subventricular (SVZ) within the telencephalon. It is one of two regions in the postnatal brain that harbors neural progenitors (NPs) capable of giving rise to new neurons. Neurogenesis in the hippocampus is restricted to the subgranular zone (SGZ)
