The number of hematopoietic stem cell (造血干细胞) donations made on the Chinese mainland has surpassed (超过) 15,000. These include 372 donations made to patients in 30 countries and regions, the China Marrow Donor Program (CMDP, 中华骨髓库) said on April 11. China saw its first hematopoietic stem cell donation in 1996. Since then, it took nearly two decades to achieve the first milestone (里程碑) of 5,000 donations and another five years to reach 10,000 donations. “This time, only two years and eight months have passed to increase by another 5,000 donations,” CMDP said. Hematopoietic stem cell donation can save the lives of patients with severe blood diseases such as leukemia (白血病).
