Regenerative medicine aims at discovering better ways of helping people after disease or injury. While most traditional therapies provide a punctual solution, the unique properties of stem cells can provide a life-long cure. However, because of the permanent aspect of stem cell therapies, their efficacy and safety have to be assessed very thoroughly. Many promising treatments are thus still being tested in laboratories. Yet, stem cell therapies are already being used, for instance to treat leukemia through bone marrow transplantation or blindness by corneal conjunctivalization through limbus grafting.
