Stem cells are at the center of a new field of science called regenerative medicine .
Because stem cells can become bone, muscle, cartilage and other specialized types of cells, they have the potential to treat many diseases, including Parkinson's, Alzheimer's, diabetes and cancer . Eventually, they may also be used to regenerate organs, reducing the need for organ transplants and related surgeries. In the same way, these stem cells can become many tissues by making certain changes in their environment. In April 2001, researchers at UCLA and the University of Pittsburgh found stem cells in fat sucked out of liposuction patients. Stem cells from fat have the ability to mature into other types of specific cells, including muscle , bone and cartilage.
