Epidermis Anatomy - Keratinocyte Maturation
Epidermis Anatomy

There are four major layers of keratinocytes (the structural cells) in the epidermis and one layer that is present only in certain parts of the body. The bottom layer, the stratum basale, has cells that are shaped like columns. In this layer the cells divide and push already formed cells into higher layers. As cells move into the higher layers, they flatten and eventually die. We will take a closer look at the characteristics of each of these layers.
