Overview

Review outlines mechanisms of cryoinjury and preservation strategies across diverse animal tissues, highlighting critical differences between post-thaw survival and functional recovery.

Key Points

To review the fundamental principles, key determinants of efficiency, and material-specific challenges associated with cryopreserving animal genetic resources.
Synthesized historical and contemporary literature addressing biophysical mechanisms of cellular cold injury, including crystallization, osmotic imbalance, and oxidative stress.
Evaluated freezing protocols, protective agents, and emerging ice-controlling materials across animal sperm, oocytes, embryos, stem cells, and gonadal tissues.
Identified ice crystal formation, severe dehydration, osmotic shock, and reactive oxygen species generation as the primary sources of cryoinjury during ultra-low temperature storage.
Demonstrated that post-thaw cellular viability does not reliably guarantee full functional recovery, with outcomes varying substantially across species and tissue types.
