Germinative cells, also known as basal cells, are primarily located in the stratum malpighii, which is the layer of the epidermis that comprises both the stratum basale (the deepest layer) and the stratum spinosum. These cells are responsible for the generation of new keratinocytes as they divide and differentiate, ultimately migrating upwards through the layers of the skin to replace dead and shed cells found in the outermost layer, the stratum corneum.

The stratum malpighii is crucial in maintaining the skin's integrity and overall health, as the continuous production of these cells helps to replenish the epidermis. The other layers mentioned do not contain germinative cells in significant quantities; for example, the stratum corneum is composed of dead keratinized cells and serves as a protective barrier, while the dermis and papillary layer primarily consist of connective tissue, blood vessels, and other supporting structures rather than the cell-generating activity characteristic of the stratum malpighii.
