The quality control for cryopreservation of many units of placental/umbilical cord blood (PCB) is a difficult problem in cord blood banking. The BioArchive System (THERMOGENESIS Co.) is a liquid nitrogen freezer tank equipped with a controlled-rate freezer and fully automated by computer intended for the cryopreservation and storage of PCB. The BioArchive System can store 3,626 units of PCB in one tank with quality control. In this study, we evaluated the usefulness of the cryopreserved PCB by using the system and the freezing bag system (Medsep). For comparison, we froze PCB in a controlled-rate freezer (CryoMed) using the Medsep bag. The recoveries of colony-forming-units were 83.2±20.3% and 84.8±22.2% in both methods (mean±SD, n=10) and there was no statistical significance. Thus, the BioArchive System can save stock space, and all the procedures are controlled by a barcode reading. These results indicated that the BioArchive System is useful for the quality control for the cryopreservation and storage of PCB in cord blood banking.
