The lowest layer of the epidermis is the stratum germinativum, also known as the stratum basale. This layer is critical for the regeneration of the skin, as it contains actively dividing cells. These cells move upward through the epidermis, eventually becoming part of the outer layers of skin. The stratum germinativum is the foundation for the entire epidermis, where new skin cells are produced.

As skin cells in this layer proliferate, they undergo a process of maturation and differentiation. This transition leads to the formation of the other layers of the epidermis, such as the stratum granulosum, stratum lucidum, and stratum corneum, which are situated above the stratum germinativum. Thus, the role of the stratum germinativum in the continual renewal and repair of skin underscores its significance as the lowest layer of the epidermis.
