With advances in science, the need for medium- and long-term storage of biological tissues, and in particular stem cells, is increasing. Storage solutions are introduced to make these tissues available for biological and medical purposes. The key issue is to ensure the integrity of the DNA molecule during storage and its suitable protection.


The cryogenised storage solution developed includes protection against natural radioactivity and cosmic rays - major issues to ensure cell protection within a long-term storage programme. It is based on designing a cryostat that meets these criteria.


Ensures the integrity of the DNA molecule and protects it during storage - especially from natural radioactivity and cosmic rays.

State of progress

A storage prototype has been designed and installed in the laboratory to begin tests on living cells. A true to scale demonstrator is currently being developed and will be available in early 2019.
