WASHINGTON, Nov. 11 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved HEMACORD, the first licensed 1 hematopoietic progenitor 2 cells-cord cell therapy.
HEMACORD is indicated for use in hematopoietic stem cell transplantation procedures in patients with disorders 3 affecting the blood forming system. For example, cord blood transplants have been used to treat patients with certain blood cancers and some inherited metabolic 4 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 Evaluation 5 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 marrow 6 and peripheral 7 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 partially 8 or fully 9 restore the number and function of many blood cells, including immune function.
