Only one-third of patients in need of bone marrow transplants receive the potentially life-saving spongy tissue from a family member.
In coming years, bone marrow may need to be sought from outside of Finland through international registers, reports Savon Sanomat.
In adults, marrow in large bones produces new blood cells. Bone marrow transplants are for instance used as a treatment method for leukaemia patients, whose own bone marrow has turned cancerous.
Some 20,000 voluntary bone marrow donors are registered with the Finnish Red Cross Blood Service. Women tend to be more active donors, as only 35 percent of donors are men.
