How is Umbilical Cord Lining Collected, Processed and Stored?
After collecting your baby’s cord blood, your obstetrician or midwife will clamp and cut a segment of the umbilical cord. This umbilical cord will be kept in a sterile container that comes with your umbilical cord lining collection kit.
The collected umbilical cord is then transported to Cordlife's laboratory for processing and cryopreservation. Before processing, a biotechnologist in our lab checks the identity of the collected umbilical cord to make sure it came from the right client. All of the steps below are done in a biohazard safety cabinet to reduce the risk of contamination before the controlled-rate freezing process.
After that, the umbilical cord is cleaned with a wash buffer solution and cut into small pieces.
To keep the stem cells in the sections of cord lining alive during cryopreservation, the sterile tissue sections are put into multiple cryovials with cryoprotectant solution.
After the cryoprotectant solution is added, the sections of cord lining are slowly frozen in the controlled-rate freezer to keep the stem cells alive.
After the controlled-rate freezing process, the cryovials are moved to an MVE vapour-phase liquid nitrogen tank where they will be kept at -190°C for a long time.
