Intriguingly, brain organoids preserved in MEDY showed similar growth and function patterns to those that had never been frozen. Incredibly, one batch was frozen in MEDY for as long as 18 months, and still showed similar protections against damage after thawing.

The team also froze samples of living brain tissue taken from a human epilepsy patient, and found that MEDY protected them from damage. The process didn’t disrupt the structure of the brain cells, and even preserved the pathologies of epilepsy – that’s important, because it means samples can be frozen for later study or analysis without damage from the freezing process confusing the results.

Very cool especially for research - hopefully this can allow for better research into how the brain functions as they're able to amass rare brain issues and study them together with this new found ability to preserve brain matter
