What do stem cells do?

Stem cells divide themselves many times to make new stem cells. They can also transform into specific cells needed by the body to heal itself. Stem cells for transplantation can come from yourself (this is called an autologous transplant) or, more commonly from a donor (this is called an allogeneic transplant).

Scientists already know how transplanted cells can be used to treat some illnesses – they're used today, mainly in allogeneic transplants, to fight various blood disorders, such as leukaemia. That's why health care professionals support public cord blood banks – they provide an opportunity for patients to find donated stem cells that match their own, just as you would with a blood type for transfusion.

As the possibilities of regenerative medicine grow, parents-to-be are increasingly choosing to save their baby's cord blood stem cells. Around the world we know that more than 250,000 cord blood units are stored in public banks – and thousands of parents across Europe and the USA have also chosen to keep their baby’s cord blood in private banks.
