(Version anglaise seulement)

Conservationists use these freezers, known as “biobanks”, to store animal cells including oocytes (egg cells), sperm and somatic cells (for example, skin cells). In the future, lost genetic diversity could be safeguarded in this way. This could be vital for the preservation of endangered species – and species that are not yet…
