Stem cells can change a person’s life dramatically. Stem cells can help provide someone with new healthy red blood cells, allowing them to recover from leukemia, Alzheimer’s, Parkinson’s. Stem cells can also help create pancreatic cells for those with diabetes. This change in a person’s life can bring new opportunities for them, such as being able to work, or being able to move. [9]

 Stem cells are prized by medical science because, unlike any other cell in the body, some are able to renew themselves indefinitely, explained Irving Weissman, professor of cancer biology and cell and developmental biology at Stanford University. Because they are unspecialized, they serve as a kind of raw material that can give rise to specialized cells that constitute blood, the brain, specific tissues such as those that make up muscle and bone, and organs such as the heart and kidneys.
