After cord blood collection, the blood is saved in bags or vials; it is taken to the cord blood bank through courier service. Once it reaches the bank, the sample is rendered a unique identification number. Thereafter, the doctors separate the stem cells from the blood and store them cryogenically (by freezing them in liquid nitrogen). After that, when needed, the cord blood stem cells are unfreeze and utilized in either Allogeneic Procedures or Autologous Procedures.
Cryopreservation
During cord blood storage, each vial is labeled with cord blood number, name of the baby, date of birth, date of processing, and the contents. Then, it enters the first stage of cryopreservation. The vials are positioned in two cryo-tanks having different temperature and then are submerged into tanks containing liquid nitrogen. This step ensures the safety of stem cells. The series of falling temperature prevents the stem cells from undergoing a shock due to the intense negative temperature of – 32 degree Fahrenheit.
Freezing The Cord Blood- Liquid Nitrogen
To prevent ice crystals from forming over the stem cells, it is important to freeze the cells gradually. For this, a particular controlled-rate freezer is used. The handling processes and the freezers are designed to prevent
