Project seeks to advance stem science without ethical problems brought by other approaches

A hospital in Zhejiang province is looking for 100 volunteers to donate menstrual blood to a research team studying stem cells, its lead researcher said.

Professor Xiang Chunsheng from Zhejiang University International Hospital in Hangzhou, who heads the project, said stem cells in menstrual blood have similar regenerative properties to those found in umbilical cords and bone marrow, both of which are currently widely studied.
