A student from the Kazakh minority at the city's Donghua University donated hematogenic stem cells at Huashan Hospital yesterday in an effort to save an ethnic Han leukemia patient in Beijing. It is the first such match between a Han and someone from a minority group.
The Kazakstani student, from a village in Fuhai County, Xinjiang Uygur Autonomous Region, signed-up for hematogenic stem cell donation when he was a university freshman, and was then recorded in the database of the Shanghai Red Cross Society.
The incidence of successful matches between ethnic Han  and people of the various minorities is very low, said Prof. Xie Yi from Huashan Hospital.
