BEIJING -- The China Marrow Donor Program (CMDP) has facilitated 10,000 donations of hematopoietic stem cells (HSC) over the past two decades, with more than 2.8 million potential donors listed on its database, according to the Red Cross Society of China.

The Red Cross Society of China presented a certificate to Lin Binbin Tuesday recognizing her as the 10,000th HSC donor. The presentation took place in Beijing at an event marking the 6th World Marrow Donor Day.

HSCs are stem cells that give rise to all blood-cell types. They are found in the bone marrow of adults and used to treat blood diseases such as leukemia.

The CMDP, established in 1992, is a non-profit organization affiliated with the Red Cross Society of China.
