 　　WASHINGTON, Nov. 11 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved HEMACORD, the first licensed1 hematopoietic progenitor2 cells-cord cell therapy.

　　HEMACORD is indicated for use in hematopoietic stem cell transplantation procedures in patients with disorders3 affecting the blood forming system. For example, cord blood transplants have been used to treat patients with certain blood cancers and some inherited metabolic4 and immune system disorders.
　　"The use of cord blood hematopoietic progenitor cell therapy offers potentially life-saving treatment options for patients with these types of disorders," said Karen Midthun, director of FDA's Center for Biologics Evaluation5 and Research, in a statement.
　　HEMACORD contains hematopoietic progenitor cells (HPCs) from human cord blood. Cord blood is one of three sources of HPCs used in transplants. The other two are bone marrow6 and peripheral7 blood. Once these HPCs are infused into patients, the cells migrate to the bone marrow where they divide and mature. When the mature cells move into the bloodstream they can partially8 or fully9 restore the number and function of many blood cells, including immune function.
