Hematopoietic stem cell potential from umbilical cord blood.
We studied the conditions of collection and isolation of hematopoietic cells from cord blood in order to optimise the sampling. A statistically significant correlation was found between the total stem cell content of the samples and the time of delivery suggesting that the quantity of hematopoietic stem cells available is higher when cord blood collection is performed earlier during pregnancy. Attempt to isolate the white cells resulted in a dramatic loss of stem cells. Factors affecting cell recovery and purification must be investigated in order to optimize cord blood cell banking.
