Germ Layer of the Epidermis

The germ layer of the epidermis (stratum cambiale) is one of the main layers of the skin, which ensures its renewal and regeneration. This layer is located under the epidermis and consists of stem cells that are in a state of rest. When the skin is damaged or other factors such as age occur, these stem cells begin to divide and migrate into the epidermis, where they form new skin cells.

The germinal layer of the epidermis is about 0.2-0.3 mm thick and is located directly under the epidermis. It contains a large number of stem cells that can differentiate into various types of skin cells such as keratinocytes, melanocytes and fibroblasts.

One of the important functions of the germinal layer of the epidermis is its ability to regenerate the skin. When epidermal cells die or are damaged, stem cells in the germ layer begin to divide and form new cells that replace the damaged ones. This allows the skin to quickly recover from injury or infection.

In addition, the germinal layer of the epidermis plays an important role in maintaining skin health. It is involved in the synthesis of collagen, elastin and other proteins that provide skin firmness and elasticity. It also contains antioxidants that protect the skin from harmful environmental factors such as ultraviolet radiation.

Overall, the epidermis is an important component of the skin and plays a key role in its renewal and protection. It ensures rapid recovery from damage and maintains healthy skin.



The epidermis is the outer, multi-layered protective shell of human skin, together with which it forms the skin. It develops from the coelomic epithelium after appearing on the germinal shield. Epidermal tissue covers the skin almost throughout the human body.

The germinal layer of the epidermis or malpighian (base of the lower epidermis) layer is the inner part of the epidermis, which is located under
