It is important to maximise the volume of cord blood that can be extracted from the umbilical cord and the amount of stem cells that can be eventually collected.
The amount of stem cells collected depends on the cell count in the cord blood. The count obtained from one collection is usually at least 200 million and counts of over 1 billion nucleated cells occur in about 25% of StemCord’s collections. Hence, most of our samples are definitely sufficient for children. Many are also enough for an adult transplant of around 50 kg in body weight. For a successful transplant, at least 10 million nucleated cells per kilogramme are needed. In collections where the nucleated cell count is high, multiple usages are feasible.
