The meeting of Karelian Registry of unrelated donors of hematopoietic stem cells representative and Chinese Marrow Donor Program delegation, which was lead by Liu Jinghu, the Deputy Director, took place on the 19th of august in Saint Petersburg. The main aim of this event, initiated by a Chinese team, was a closer cooperation in marrow donors search in the registries of these two countries. In particular, our foreign colleagues were interested in the possibility to search donors in our registry database for Chinese people, residing in Russia (Chinese expat community in Russian Federation has around 100 000 people). Liu Jinghu told us about their Chinese registry which has now almost 1 million donors. 2 300 of them became real donors, implemented donation, 85% of them – for Chinese patients, and 15% - for patients from another countries. As a result we agreed on cooperation for donors search in Chinese and Karelian registries databases. Karelian registry representative was invited to visit Chinese registry of bone marrow donors.
