STEM CELLS ARE the body’s founder cells, which form into all the specialised cells that make up the body (blood, muscle, bones, nerves, connective tissue, organs and skin). Stem cells have these three features:
■ They can divide and renew themselves for long periods of time.
■ They’re unspecialised cells.
■ These cells can turn into or become specialised types of cells.
WHAT DO THEY DO?
They function as a kind of repair system
