Cord blood, also called placental blood, is the blood that is present in the placenta and in the umbilical cord. It is interesting from a medical point of view because it contains hematopoietic stem cells, which produce throughout our life all the cells present in the blood: red blood cells that carry oxygen; white blood cells that fight infections; platelets that stop bleeding.

Hematopoietic stem cells are also found in the bone marrow. Cord blood also has got numerous different medical applications. And some people even choose to donate their umbilical cord blood to public banks so that they can donate them to other people.
