My name is Josie Minks and I'm a labor and delivery nurse in Austin, Texas and I'm going to be talking to you about how long cord blood can be stored. So cord blood is taken at delivery. Once the doctor clamps the cord and takes it from the placenta, a representative from either a private or public cord blood collection facility will come and take the blood and take it to the facility where it's separated from the stem cells and the other blood products and then the stem cells are stored cryogenically, which means it's frozen in liquid nitrogen and can be stored for forever. But, studies have only been done since the nineteen-seventies and so we're not really sure for how long forever can be, as far as we know, it can be stored for forever, and so that is how long the cord blood can be stored.
