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
Umbilical cord also found in a study from 2008. Although there is higher hemoglobin level at 2 months, this effect did not persist beyond 6 months of age. Not clamping the cord for three minutes following the birth of a baby improved outcomes at four years of age. A delay of three minutes or more in umbilical cord clamping after birth reduce the prevalence of anemia in infants. Negative effects of delayed cord clamping include an increased risk of polycythemia. Still, this condition appeared to be benign in studies. Infants whose cord clamping occurred later than 60 seconds after birth had a
