Biotechnology Innovation Medical Logistics Synthetic Biology

Researchers from the University of Michigan and the University of Chicago have discovered that a specific protein from tardigrades, CAHS12, can protect synthetic cells during dehydration. This finding suggests a potential method for storing and transporting biological products, such as vaccines, without the need for continuous refrigeration.

“A protein found only in microscopic tardigrades, one that allows them to survive extreme conditions like dehydration, can convey similar durability in synthetic cells”
CORROBORATED
Multiple sources, including a specific report on CAHS12 and a Nature Communications abstract, confirm that tardigrade proteins (specifically CAHS) enable synthetic cells to survive dehydration by forming a protective network.
