How can it happen that the storage of stem cells is sometimes unsuccessful?
Sometimes the quantity of blood collected is simply too small, which means that not enough stem cells can be isolated. Another problem may be the contamination of the sample by bacteria, fungi or viruses. In order to reduce this risk, the cord blood should be collected in the most sterile conditions possible. The average success rate for storing stem cells from cord blood is more than 90 percent. Reading and carefully following the instructions supplied increases the chances of success.
