Bone marrow is a "spongy" tissue that fills the inside of many bones and their cavities. It is in this tissue that there are progenitor cells, i.e. cells with the capacity to differentiate and give rise to any cell in the peripheral blood, the so-called progenitor/stem cells. These cells constantly renew themselves, maintaining a relatively constant number throughout life. (source: sns)

Did you know that bone marrow transplants are often the only way to cure serious and fatal diseases such as lymphomas, leukaemias, severe anaemias, among others, and that around 80% of everyone has a potential compatible donor and this is the only way to cure them?

Donating bone marrow is a simple and safe act that helps save lives. Contrary to popular belief, it is possible to make more than one donation. Bone marrow is a tissue that regenerates quickly, so it is possible to make more than one donation.

Surgery is not the only way to donate bone marrow and there are no negative impacts for the donor. Almost 80% of the time, the marrow is extracted using a process called apheresis, which doesn't involve surgery and is similar to a blood transfusion. The donor may feel only slight discomfort and goes home the same day. (source: news magazine)
