Cord blood: the basics – WMDA

What is cord blood?

After a baby is born and the umbilical cord is cut, some blood remains in the blood vessels of the placenta and the portion of the umbilical cord that remains attached. This is called umbilical cord blood, or ‘cord blood’ for short. Cord blood contains all the normal elements of blood: red blood cells, white blood cells, platelets and plasma. But it is also rich in blood stem cells, similar to those found in bone marrow. The European Directorate for the Quality of Medicines & Healthcare published a guide for parents, which you find here. Also, the Cord Blood Association provides valuable information on their website.
