So far, scientists have identified several different types of skin stem cell: 1  Epidermal stem cells are responsible for everyday regeneration of the different layers of the epidermis.2  These stem cells are found in the basal layer of the epidermis. 3  Hair follicle stem cells ensure constant renewal of the hair follicles.o far, scientists have identified several different types of skin stem cell: 1  Epidermal stem cells are responsible for everyday regeneration of the different layers of the epidermis. 2  These stem cells are found in the basal layer of the epidermis.
Most of the time, each cell has a specific job to do. One cell can't do what another cell can, just as a doctor isn't trained to design a bridge and an engineer can't do surgery. So cells work as a team, grouping together to make up our tissues and organs. But one type of cell is different. Stem cells can develop into cells with different skills. In that way, stem cells are like students who have the choice of studying to be either doctors or engineers. None of the body's other cells can become new cells like this. Blood Stem Cells.
