How are stem cells frozen and stored? Where is the storage location?


Cord Blood:

At Maze Cord Blood, once your cord blood has been processed, we store the stem cells in tanks holding vapor nitrogen at optimal long-term storage temperatures -190º C or colder. We use vapor nitrogen rather than liquid nitrogen due to vapor’s ability to remain at a consistent temperature throughout the tank.

Additionally, using vapor nitrogen protects the frozen cord blood from any infections or bacteria, which are able to “swim” through liquid nitrogen and infect other cord blood specimens.

Your baby’s cord blood is stored in 2 compartments (25ml and 5ml). There are also small test vials available to check for genetic matches if needed in the future.


Cord Tissue:

When storing your baby’s cord tissue, MazeT5TM Multi-Compartment Storage preserves the unique stem cells from your baby’s cord tissue in 5 equal and separate segments.

This offers your family the most options for the future, providing flexibility to use only a part of these valuable stem cells as needed.

Where are the stem cells stored?

The permanent storage is in the Maze cryogenic facility in Purchase, NY. Our lab is continuously inspected and assessed by the FDA for compliance, and has been FDA approved since 1997.

Our tank’s temperature is monitored electronically with readings every hour, and we have two levels of back-up alarm systems should the temperature be compromised in any way. If the temperature increases even slightly, the alarm sounds. The alarm is then sent through an automatic calling system to alert our staff, one of whom is on call at all times to immediately resolve the situation. The system has a large back up battery and then a backup generator connected to this.
