Stem cells are what all cells in your body are before they became your organs and everything (they are the stem from which your body grows). As your body develops, they differentiate into all of the organs, which then grow into you. Whether it’s your liver, skin, nerves, eyes brain, at one point they were all stem cells.
Adult stem cells eventually lose their ability to differentiate and just kind of exist, but we have recently learned how to make them differentiate again. This gives us the ability to heal wounds we thought weren’t possible before by literally rebuilding the structure.
The harvesting process for stem cells is also very easy. They just take your blood and filter out the stem cells.
