Chinanews, Shanghai, September 3 – Shanghai will build a cord-blood bank storing at least 10,000 samples at a time in 2010, to meet the increasing demand for hematopoietic stem cells transplant. Theoretically, the cord-blood bank will serve as a bone marrow bank with about 100,000 to 500,000 donors.The hematopoietic stem cells in cord-blood can be used to treat some 80 kinds of diseases. Besides, it is more likely for patients to find appropriate cord-blood than suitable bone marrow donors, not to mention that cord-blood transplant usually leads to much lighter side-effects than bone marrow transplant.Last year, only 3,000 mothers donated or kept the cord-blood of their babies, accounting for only 2% of the total new mothers that year. The collection of cord-blood is after cutting off the umbilical cord, thus no harm or pain will be caused to the baby.The cord-blood can also be used without side-effects to cure the hematopoiesis disease of the baby if it unfortunately afflicted with such diseases
