Stem cells can redevelop into multiple cell types in the body. They can also be used as a repair system inside the body for tissues and can replenish other cells already present. When stem cells divide, each cell that comes from the division can remain a stem cell or transform into another cell type with a new function—such as transforming into a red blood cell or brain cell. For a cell to be considered a stem cell it must contain two unique properties:
1) it must be able to renew itself through cell division—even after long periods of inactivity;
2) under certain conditions it must be able to transform into multiple cell types, such as bone marrow, tissues or organs.
Scientists have historically worked with two types of stem cells: embryonic and somatic (non-embryonic). Stem cells carry unique regenerative properties and have a high potential for curing disease. While the research is ongoing, researchers are much closer to using stem cell therapies to treat patients.
