What is the stratum germinativum also referred to as?

The stratum germinativum is also known as the basal layer. This layer is the deepest part of the epidermis and plays a crucial role in the regeneration of skin cells. It contains actively dividing keratinocytes that continue to produce new skin cells, which gradually move upward through the layers of the epidermis as they mature. The presence of melanocytes in the basal layer is important for pigmentation, as these cells produce melanin, which is responsible for skin color.

As skin cells progress from the stratum germinativum to the surface, they undergo a process of keratinization, becoming more flattened and filled with keratin. This contributes to the protective barrier function of the skin. The basal layer is essential for skin health and healing, as it ensures a continuous supply of new cells to replace those that are shed or damaged.
