Umbilical Cord Blood Donation

Umbilical cord blood is the blood that remains in the umbilical cord and placenta after a child is born and the cord has been cut. This cord blood contains millions of valuable stem cells that can be transplanted in precisely the same way as stem cells and bone marrow. In Germany, the significance of cord blood donation has declined due to the widespread willingness of potential donors and is therefore rarely undertaken, unlike in other countries. In exceptional cases and if the search for a donor proves particularly difficult, however, cord blood will still be used in Germany.



Low risk of infection during transplantation Limited quantity of stem cells that often will not suffice for transplantation in adults
Low-risk donation Delayed blood formation in the patient after transplantation (aplasia)
Donated cells available immediately Possibly undetected genetic disposition for serious diseases
Laborious process of donor preparation unnecessary
Increased immunological tolerance if the HLA characteristics of the donated cells and recipient do not match exactly

Collection of umbilical cord blood

After birth, the vein at the end of the cord is punctured to drain the residual blood from the umbilical cord and placenta into a special collection system. This is transported to a cord blood bank, where it is centrifuged. The cell concentrate thus obtained is mixed with a preservative solution and stored in liquid nitrogen at -135°C.

Parents can choose between two options: While storage in a public cord blood bank is free of charge and the stem cells from the cord blood can be made available to any patient worldwide, commercial, private cord blood banks offer individual donors storage, for a fee, in the event that they require the service themselves in the future. With some diseases, however, such as congenital conditions, the cord blood is already affected and thus cannot be used for transplantation.

Reasons for ruling out a cord blood donation

A pregnant woman may not donate umbilical cord blood if any of the following applies to the mother, father, or a member of the family:

  • Mother under 18 years of age
  • Complications during pregnancy
  • Certain illnesses in the mother or the (biological) father
  • Severe infectious diseases in the mother (e.g. HIV or hepatitis)
  • Addiction in the mother
  • Genetic diseases in the family
  • Mother belongs to a risk group according to the guidelines of the German Medical Association
