The sources of stem cells include embryos, amniotic fluid, bone marrow, and adult blood. However, the umbilical cord is the best source and offers the safest method of stem cell extraction. Umbilical cord storage provides vital support to the hospitals that offer stem cell therapy.
What is Umbilical Cord Blood Banking
The umbilical cord is a structure that connects a fetus or baby with the mother for nutrition and excretion of metabolic waste produced in the baby. Structurally, it houses a bloodstream that allows the exchange of materials between fetal and maternal blood. A few minutes after the child's birth, gynecologists deliver the placenta and umbilical cord.

A phlebotomist from a cord blood bank draws blood from the cord into a sterile collecting bag when parents opt for cord blood preservation. The blood bank then samples the blood to run tests to check for the presence of disease-causing agents, such as viruses and bacteria. Once the examinations show clearance, they store the blood at about minus 196 degrees Celsius.
Types of Cord Blood Bank

What are Umbilical Cord Preservation Benefits
- Umbilical cord blood contains hematopoietic stem cells, which have the potential to reconstitute any blood cell type. Hence, it can treat life-threatening diseases, including acute lymphocytic leukaemia, Neuroblastoma, Myelodysplastic syndrome, sickle cell anaemia, and thalassemia.
- The maximum shelf life of cord blood from a baby is 21 years but any biological sample stored below or at minus 150 degree centigrade does not have any shelf life. Hence, cord blood preservation provides insurance for a life-threatening disease diagnosed before the expiry of the blood.
- Moreover, the parents can donate blood to someone suffering from a deadly disease and help save their life.
- During the storage, every cord blood bank performs HLA typing on the blood to identify the markers unique to the baby. When the HLA typing of the baby matches with a person diagnosed with a genetic disease, the parents can donate the blood for the treatment.
