These are progenitor cells that can self-renew through mitosis and that have the capacity to regenerate one or more types of differentiated cells.
There are adult stem cell populations in the various tissues that are responsible for periodic renewal, regeneration and repair when damage occurs (acting as reserve cells).
Stem cells have the ability to divide (without losing their properties) and generate new cells. They are the foundation of the cell renewal process so their protection and restoration is essential.
Thousands of epidermal cells may be renewed by each protected stem cell, repairing the effects of skin aging. Skin stem cells are direct precursors of the cells found in the different skin layers. Thanks to their ability to differentiate, they can regenerate aged tissues.
