Your child’s stem cells are stored in a secure facility and maintained at -196.5 degrees centigrade. The process is known as Cryopreservation, the cells are essentially frozen and preserved in the state of ‘suspended animation’. The process uses the vapour of liquid nitrogen, which means the storage of samples are not dependent on electricity supply, therefore they are not at risk in a power outage. Numerous surveillance and monitoring processes are in place to keep the samples safe.
