In the event that your child ever requires stem cells, it is often difficult or even impossible to find a perfect match from a bone marrow donor or the umbilical cord blood from another donor. Your child’s own stem cells are a perfect match to your child with no chance of rejection. By banking your child’s cord blood, you are ensuring that your child will have a supply of his/her own stem cells which are a perfect match to himself/herself which can be used for transplantation and therapy without fear of rejection or the inability to find a matching donor in time to treat the disease.
