Abstract
Cryopreservation of cells and biologics underpins all biomedical research from routine sample storage to emerging cell-based therapies, as well as ensuring cell banks provide authenticated, stable and consistent cell products. This field began with the discovery and wide adoption of glycerol and dimethyl sulfoxide as cryoprotectants over 60 years ago, but these tools do not work for all cells and are not ideal for all workflows. In this Review, we highlight and critically review the approaches to discover, and apply, new chemical tools for cryopreservation. We summarize the key (and complex) damage pathways during cellular cryopreservation and how each can be addressed. Bio-inspired approaches, such as those based on extremophiles, are also discussed. We describe both small-molecule-based and macromolecular-based strategies, including ice binders, ice nucleators, ice nucleation inhibitors and emerging materials whose exact mechanism has yet to be understood. Finally, looking towards the future of the field, the application of bottom-up molecular modelling, library-based discovery approaches and materials science tools, which are set to transform cryopreservation strategies, are also included. Cryopreservation is a platform technology that underpins the delivery of complex therapies to patients and enables fundamental cell biology by allowing the banking and recovery of viable cells. This Review summarizes the role, and opportunities, for chemistry-driven approaches to cryopreservation, beyond formulation, to the design and discovery of innovative solutions.
期刊介绍:
Nature Reviews Chemistry is an online-only journal that publishes Reviews, Perspectives, and Comments on various disciplines within chemistry. The Reviews aim to offer balanced and objective analyses of selected topics, providing clear descriptions of relevant scientific literature. The content is designed to be accessible to recent graduates in any chemistry-related discipline while also offering insights for principal investigators and industry-based research scientists. Additionally, Reviews should provide the authors' perspectives on future directions and opinions regarding the major challenges faced by researchers in the field.
