How Long Does Stored Cord Blood Last?


Once removed from the umbilical cord and properly cryogenically frozen and preserved, cord blood should last forever. Again, this cannot be confirmed as the concept of this umbilical cord blood banking is relatively new. It started in the 1970s and as of yet there isn’t sufficient evidence available that will definitively prove that your babys umbilical cord blood will last their entire lives. Nevertheless, research shows that this blood saved for over fifteen years has been used successfully in transplants.

The Process of Storing Cord Blood


Interested in the process behind umbilical cord blood storage? Here is an overview of how stem cells are preserved after being taken from the umbilical cord.

The cord blood is stored in specially designed bags or syringes and couriered to the blood bank centre, where it is then labeled with the donors name, date of birth and other relevant details. The cord blood is given a registration number by which it can be identified and is then sent for processing. The cryopreserving process is that the temperature of the blood is slowly reduced in order to avoid a temperature shock (minus 321 degrees Fahrenheit) after which the umbilical blood is transferred to liquid nitrogen tanks where the temperature stays steady at minus 321 degrees. Very special procedures are performed to ensure that the cells don’t get frozen ice on them, which would damage the cell membranes.
