FROZEN HUMAN BRAIN TISSUE WAS SUCCESSFULLY REVIVED FOR THE FIRST TIME

Summary from the TLDR newsletter

Scientists from China have found a way to thaw human brain tissue without damaging it. The scientists grew brain organoids from human embryonic stem cells and then tested various chemical compounds to determine which combinations could help keep frozen human brain tissue alive and enable growth after thawing. The most successful combination consisted of methylcellulose, ethylene glycol, DMSO, and Y27632. The researchers suspect it somehow interferes with a pathway that would otherwise initiate cell death, allowing for the issue to freeze and be thawed without incident.
