This study, published in the Animal Science section of the Peer Community Journal, proposes an analytical framework and indicators for the evaluation of cryopreserved animal collections for the conservation of genetic diversity. These indicators can be calculated at regular intervals to help plan and manage these collections at national and international levels, and to help population managers exploit the resources currently available. This analytical framework has been applied to the French national cryobank.

Stem cells and organoids - simplified versions of organs - are biological tools that have enabled major advances in biology and medicine. What prospects do these tools offer for research on animal species of agronomic interest? How can they replace or complement animal experimentation?
