Multiple sclerosis (MS) is caused by the immune system getting it wrong and mistakenly seeing the myelin coating (which protects nerves) as a foreign body. The immune system consequentially attacks the myelin leaving scaring and lesions which interfere with the ability of nerves to transmit messages.
Hematopoietic stem cell transplant (HSCT) aims to reset the immune system to prevent further damage.
The HSCT treatment is a process involving chemotherapy to destroy the immune system. The immune system is then rebuilt with a transplant of haematopoietic stem cells, normally taken from bone marrow or blood.
