Scientists have discovered that some adult human body tissues, such as bone marrow and fat, also contain cells that can function as stem cells. Adult stem cells are multipotent, however, which means that they can become only a limited number of types of tissues and cells in the body. Embryonic stem cells have a greater potential to treat a wider variety of diseases because they are pluripotent—they can become almost all types of tissues and cells in the body.
