- What is a Hematopoietic Stem Cell?
Hematopoietic stem cells are hematopoietic tissues that make blood in our bones. Red corpuscles, white corpuscles, blood platelets, etc. in the blood are made in these cells.
Many patients suffering from intractable blood tumor including leukemia and aplastic anemia who are unable to make normal blood due to the abnormality of their hematopoietic stem cells die from severe anemia, infection, bleeding, etc..

- Why is Hematopoietic Stem Cell Donation Necessary?
Leukemia which was once known as an incurable disease can be completely cured if the patient is receives a hematopoietic stem cell transplant(bone marrow, Cord Blood) from a healthy person after eradicating his own hematopoietic stem cells(bone marrow).
In this case, success of the transplantation depends on the HLA as donor geneotypes should fully coincide with that of the recipient. The overall probability of coincidence is four out of one in case of siblings and one out of thousands or millions in case of non-blood relative donors.
When a patient is suffering from leukemia, it is impossible to test thousands or millions of people and find a donor in person if he/she does not have a sibling whose HLA matches with himself/herself.
Therefore, we should find healthy donation seekers who are willing to donate their hematopoietic stem cells(bone marrow, Cord Blood), conduct an HLA testing, save the results in the computer of the central organization and match donors’ information with patients to coordinate a transplantation for those who are in need of a hematopoietic stem cell transplant(bone marrow, Cord Blood).
