Due to the lack of evidence that stem cells derived from stored cord blood units remain viable, potent and suitable for administration after storage for lifetime. 

Currently available data obtained from stability studies do not provide any scientific evidence that stem cells derived from cord blood units remain viable, potent and suitable for administration after storage for lifetime.

Many variable parameters that may impact the expiration date of a stored cord blood unit such as the procedures used in collection, processing, cryopreservation and final storage container of stored cord blood units.

There is no published stability studies on stored cord blood units to verify the successful "lifetime" viability and potency of cord blood derived stem cells collected, processed, cryopreserved and stored using different procedures performed by different Cord Blood Banks at the national and international levels.
