With over 125,000 Greek-Cypriot and Turkish-Cypriot volunteer donors registered, the Bone Marrow Donor Registry of Karaiskakio Foundation represents the biggest per capita Donor Registry worldwide. The Registry operates under strict rules and has been accredited by the World Marrow Donor Association (WMDA) since 2008. The importance of the Bone Marrow Donor Registry, for the Cypriot patients residing in Cyprus and abroad, is immense since the chance of finding a matching donor is greater amongst people of the same descend. In addition, the Cypriot Bone Marrow Donor Registry dynamically participates in the International Donor Registry giving Cypriot volunteer donors the opportunity to donate to any patient requiring a bone marrow transplant worldwide.
