Project Overview

Cryopreservation is a vanguard discipline that refers to the preservation of cells, tissues or organs at cryogenic temperatures, especially at -130˚C or below, and is crucial in cryonics. For successful cryopreservation, cryoprotectants (also known as cryoprotective agents, or CPAs), which are chemicals used to protect biological systems from freezing damage, are usually required. For at least some organs, they are believed to be needed in concentrations high enough to prevent the formation of ice crystals during cooling allowing instead preservation in a glassy state. This glassy state form of preservation, known as vitrification, is a challenge to achieve. Organs need to be able to survive not only “cooling injury” (injury caused by cooling per se) , and osmotic damage but also the direct biochemical effects of perfusion with the extremely high concentrations of CPAs that are required for the organs to be successfully vitrified. Unfortunately, there is currently little detailed information available regarding the toxicological and biochemical effects of these chemical agents.

This study aims to discern mechanisms of cryopreservation-related injury, and specifically pertaining to CPAs, using gene expression profiling. Very few studies have profiled gene expression in the context of cryopreservation, and more data are needed to elucidate molecular mechanisms in more systems. With the data generated we will employ machine learning and computational models to predict new, safer combinations of cryoprotectants. We will use this approach to create a patentable computational model to improve cryoprotectants used for primary cell lines.

Simple Summary:

Generate a unique large dataset of cryoprotectant molecular profiling in vitro and use it together with machine learning and computational models to predict new, safer combinations of cryoprotectants, new potential cryoprotectants and toxicity neutralizers for the preservation of primary cell lines.


  • High impact for cryopreservation
  • Solid evidence supporting their approach
  • All required technology established in lab
  • Patent would have direct commercial potential
  • Pre-clinical applications (e.g. cell preservation for research)
  • Comparatively low funding required
  • No university overhead, private lab without TTO/third party approval required 


  • Short term commercialization might not be easy
  • Technical risk

Total: 6-month personnel + running costs - USD 50,000

No overhead 

Conflict of Interest Statement:

One core member (Emil F. Kendziorra) is involved and a minority shareholder in Oxford Cryotechnology. All funds will only be used for direct project cost, EFK is not receiving a salary or other compensation from the funds provided but might benefit from the IP-NFT if successful.
Furthermore, EFK will abstain from all voting. 


While Cell, Organ and Human Cryopreservation holds tremendous potential it is still a majorly underfunded sector of the longevity and life extension ecosystem. Very little is known about how CPA toxicity can be reduced while maintaining other beneficial properties, especially at the high concentrations needed for vitrification. In vivo toxic mechanisms, including conversion to toxic by-products by the liver, are presumably not operative outside the body at low temperatures and, therefore, do not provide guidance as to how toxicity may be avoided during organ vitrification. Reducing toxicity is of utmost importance to not only allow for the potential of cell and organ preservation but to improve the chances of successful resuscitation of cryopreserved humans in the future.


Oxford Cryotechnology aims to significantly and relevantly improve the preservation of cells, complex tissues and ultimately enable the capability to cryopreserve and store organs and human beings. To this end, new formulations for cryopreservation and novel cryoprotective agents (CPAs) will be identified in order to maximise post-thaw cell and tissue viability. Our approach will provide insights into the toxicity mechanisms of cryoprotectants in human cells. Overall, Oxford Cryotechnology will establish a novel, interdisciplinary approach to disrupt traditional cryopreservation and accelerate the development of computationally assisted protocols for cell, and potentially whole-organ and body cryopreservation. If successful, this project has tremendous short- and long-term impact and commercialization potential.
