Cord blood storage
Cord blood preservation
The preservation of umbilical cord blood and tissue requires storage in specialized facilities to preserve their viability and integrity for future use.
The longevity of the preservation depends on the type of storage and the quality of the preservation process.
Cryopreservation of cord blood banking
There are currently two main methods of preserving umbilical cord blood and tissue: cryopreservation and cryogenic freezing.
Cryopreservation: Cord blood can be cryopreserved, typically by using a cryoprotectant solution and freezing at very low temperatures, typically around -196 degrees Celsius (-321 degrees Fahrenheit).
Umbilical cord blood stored under these conditions can be stored for long periods of time, with some facilities reporting a shelf life of up to 25 years or more.
It should be noted that while cord blood can potentially be stored for several decades, the longer it is stored, the greater the risk of cell damage or loss of viability.
Cryogenic Freezing of cord blood banking
Cryogenic Freezing: Some companies also offer cryogenic freezing of umbilical cord tissue, which uses liquid nitrogen to keep the tissue at extremely low temperatures.
This storage method is relatively newer than cord blood storage. The long-term storage potential of umbilical cord tissue is still being explored, but is expected to have a shelf life similar to cord blood, with claims of up to 25 years or more.
It must be said that the above preservation time is the maximum limit recommended by some magazines.
However, as technology advances and research continues, it is possible that preservation methods will improve, resulting in an even longer shelf life.
It is always advisable to consult cord blood banks for the most accurate and up-to-date information on storage options and expected storage times.
