"Every family knows they are one phone call or one diagnosis away from needing what stem cell research can yield for us." - Speaker Nancy Pelosi U.S. House of Representatives
Stem cells have the unique ability to divide and form all the different types of mature tissue or organ specific cells in the body, such as muscle, lungs, brain, heart, or skin. They can also limitlessly divide and create an identical copy of themselves – a process called self-renewal.
