Interesting Fact:
Stem cells are unspecialized cells that serve as the source, or "stem," for specialized cells like heart, brain, or blood cells. Found in days-old embryos and a few adult organs, stem cells have two unique properties: they can change into other types of cells, and theoretically, they can divide without limit. |
