PathCare's stem cell storage facility is designed to meet the most stable and precise cryogenic temperature control, while avoiding sample exposure to liquid nitrogen, which can transfer viruses, risking cross-contamination. Each sample is encased in an outer protective layer to ensure the barcode never detaches from the sample. This system provides the most secure and long-term storage.

If the samples are found to be fit after processing, we store the stem cells in cyro bags (20 ml main cyro-bag and 5 ml satellite cyro-storage bag). This provides the family a significant benefit in the future, since the cells may be used for more than one treatment. We use a small portion of the baby’s own plasma and Dimethyl Sulfoxide (DMSO) which acts as a cyro-protectant to protect the cells and keeps it internal structure intact. The DMSO solution can be spun out of the cell in the future, when it needed for transplant and cells can be washed off.

The samples are then immediately transferred to liquid nitrogen storage tank maintained at -196°C in vapour phase. Each client sample is suspended in vapour-phase cryogenic isolation, which protects the stem cells and eliminates the risk of cross-contamination from other samples that can occur in liquid phase storage.
