The Skin

Obviously, skin is a very important tissue for human-beings. It allows us to feel many different things in our daily life, such as pressure or heat, and more importantly it protects us from infection and dehydration.

The epidermis part forms the surface of the skin, and it is comprised of several layers of cells called keratinocytes. While the dermis part lies underneath the epidermis and contains skin appendages: hair follicles, sebaceous (oil) glands and sweat glands. The rest subcutis includes fat cells and some sweat glands.

Our skin has to be constantly renewed throughout our lives, because we rely the skin to cope with a lot of wear and tear everyday, to repair skin damage efficiently, and to keep itself in good condition. All of this relies on a whole host of different stem cells, including epidermal stem cells, hair follicle stem cells, melanocyte stem cells.

• Epidermal stem cells are found in the basal layer of the epidermis, and are in charge of daily regeneration of the different layers of the epidermis.

• Hair follicle stem cells are found throughout the hair follicles. They are responsible for constant renewal of the hair follicles, as well as regenerating the epidermis and sebaceous glands if these tissues are damaged.
