Blood & marrow
Looks like
Unspecialised cells found in the embryo and in small numbers in adult tissues such as marrow, skin and gut.
What it does
Divide to renew themselves and to make the specialised cells that replace worn-out tissue.
Keeping it well
Bone marrow transplants are the established stem cell treatment. Clinics selling unproven stem cell injections carry real risks.
