Nigeria: Bone marrow register an 'important milestone'

Only a fraction of the millions of people worldwide with blood and autoimmune disorders survive - especially those in poorer countries - partly due to the lack of bone marrow stem cell transplants. A recently established Nigerian bone marrow registry hopes to boost matches between donors and patients, and survival chances. Some 200,000 babies are born annually in sub-Saharan Africa with sickle cell disease, a blood disorder in which mutated red blood cells can clump and block blood vessels, causing pain, infection and organ damage. Nigeria has up to two million sickle cell patients, many of whom can benefit from stem cell transplants.
