Are all stem cells the same? Where are they in the skin?

by admin

Each individual organ of the body has its own specific adult stem cells. The skin, for example, is not one unit as many people think but rather is comprised of two different layers, the outer Epidermis and the inner Dermis. Therefore, it has two distinct populations of adult stem cells: epidermal stem cells and dermal stem cells.
Although the dermis is the important layer of the skin where all the collagen & elastin are manufactured, the exact location in the skin of the dermal stem cells’ reservoir was very hard to find and was only recently discovered in December 2009.
