We all have stem cells at work inside us all the time. At any single moment, inside your bone marrow, stem cells are busy making the 100,000 million new blood cells you need every single day! We need to make new cells all the time, just to keep our body functioning. Some specialized cells, such as blood and muscle cells, are unable to make copies of themselves through cell division. Instead they are replenished from populations of stem cells. Stem cells have the unique ability to produce both copies of themselves (self-renewal) and other more specialized cell types (differentiation) every time they divide. Stem cells, therefore, are essential to the maintenance of tissues such as blood, skin, and gut that undergo continuous turnover (cell replacement), and muscle, which can be built up according to the body’s needs and is often damaged during physical exertion.
