stem cells are the precursors of all other cell types in the body. what makes stem cells special is that they are regenerative. regenerative medicine is a growing field that offers the potential to repair and replace damaged tissues and organs by using those that are specially grown. stem cell transplantation was pioneered using bone-marrow-derived stem cells by a team at the fred hutchinson cancer research center from the 1950s through the 1970s led by e. donnall thomas, whose work was later recognized with a nobel prize in physiology or medicine in 1990 |
