![]() ![]() Generally, there are three processing methods utilized in the field. Validation provides data to demonstrate the procedure works consistently and effectively at each facility. It is very important for facilities to validate the procedures used. Methods for this part of the process vary. The product is then reduced of the red cell and/or plasma components in preparation for cryopreservation (freezing). When UCB is received at a processing facility, the unit and accompanying paperwork are inspected and reviewed. How do these techniques work? What is the best way to process and store cord blood?Ĭord blood banks use a variety of processing and storage techniques, with each option offering advantages and disadvantages. ![]() Top The facilities I’ve contacted all use different processing and storage techniques. If this is not possible, other options such as partial consent before delivery and follow-up after delivery may be utilized for public banking. What is involved and is not distracted or under anesthesia. In public donation, consent should begin before the onset of labor when the donating mother is able to fully understand This would include consent for storage and infectious disease testing. Into an agreement at any point during the pregnancy. For private storage, the mother may enter This ideally happens after reviewing information with her obstetrician during the last trimester. Each mother must be informed about cord blood collection and give consent for collection and testing. Varies but usually ranges from 50 to 200 ml (about one-half to one cup). The UCB product is labeled and shipped to the processing facility for processing, freezing and storage. The collection may take place either before or after delivery of the placenta, and techniques vary slightly among physicians. Since this happens after delivery, there is no pain or risk to mother or infant. A needle is then used to draw the blood from the umbilical cord vein into a collection bag. Source of stem cells - which must be matched by tissue type to some degree with the recipient - must be made by each patient in consultation with his or her physician based on available options.Īfter the delivery of a newborn, the umbilical cord is clamped and then cut. Each source of HPCs (bone marrow, peripheral blood or cord blood) has advantages and disadvantages associated with its use in a transplant. Other uses of UCB stem cells are currently undergoing research. UCB contains many types of blood cells but only the hematopoietic - or blood-making - stem cells in the UCB are currently usefulįor transplant. Replenish a patient’s immune system by providing stem cells for transplantation, just as bone marrow or peripheral blood stem cell transplants can be used to treat malignant diseases such as leukemia and non-malignant diseases such as immuneĭeficiencies and severe aplastic anemia, and congenital disorders such as sickle cell anemia and thalassemia. Umbilical cord blood (UCB), once regarded as biological waste, has become an accepted source of hematopoietic stem cells/hematopoietic progenitor cells (HSCs/HPCs), similar to those found in bone marrow and peripheral blood. What if there is a genetic disease in my family? What are umbilical cord blood cells? I’ve heard that they may be able to use cord blood to treat heart disease, spinal injuries and other disorders. What are the chances I will need my child’s UCB product? Should cord blood be stored in bags or vials? ![]() How do these techniques work? What is the best way to process and store cord blood?
