Cord blood dose, however this amount varies from infant to infant and is irreplaceable. Given that this idea is quite new, there is still a lot of research that needs to be completed. For example, it is still unknown how long cord blood can safely be frozen without losing its beneficial effects . There is a lower incidence with cord blood compared with traditional HSCT, despite less stringent HLA match requirements. Umbilical cord blood is the blood left over in the placenta and in the umbilical cord after the birth of the baby. There are several methods for collecting cord blood. The
Cord blood method most commonly used in clinical practice is the "closed technique", which is similar to standard blood collection techniques. With this method, the technician cannulates the vein of the severed umbilical cord using a needle that is connected to a blood bag, and cord blood flows through the needle into the bag. On average, the closed technique enables collection of about 75 ml of cord blood. Collected cord blood is cryopreserved and then stored in a cord blood bank for future transplantation. Cord blood collection is typically depleted of red blood cells before cryopreservation to ensure high rates of stem
