Your body is made up of two different types of cells, somatic cells and stem cells.
Somatic cells form the body we see and feel and help it function. There are trillions of these specialized cells in your body: heart cells, lung cells, red blood cells and so forth each carry out a specialized function to keep it running.
Stem cells repair tissues that have been damaged through normal wear and tear, injury and disease, or poor lifestyle choices. These unspecialized cells have a restorative quality that allows them to renew tissues by replacing somatic cells that have worn out or no longer function at optimal levels.1
Stem cells are much fewer in number than somatic cells and somewhat harder to find; they primarily live in the bone marrow, but are also found in the2:
