Researchers at Texas A&M University have developed a new method to reduce cracking during cryopreservation. This breakthrough could lead to longer-lasting transplanted organs and help in various fields like medicine, conservation, and food storage.

Cryopreservation is a process that preserves biological tissue by cooling it to extremely low temperatures. Scientists have been studying this technique for nearly a century, but progress was slow until 2023 when researchers at the University of Minnesota successfully transplanted a cryopreserved kidney into another rat. This milestone showed that frozen organs could one day be used in human transplants.

However, preserving larger organs remains a major challenge. One of the biggest problems is cracking, which can occur when tissues are cooled too quickly. These fractures can damage the organ and make it unusable.

A team at Texas A&M University, led by Dr. Matthew Powell-Palm from the J. Mike Walker '66 Department of Mechanical Engineering, has introduced a new approach to address this issue. Their research outlines a method that could reduce the likelihood of cracking during cryopreservation.

The team's findings suggest that higher glass transition temperatures can reduce the risk of cracking. This discovery gives scientists a clearer direction for improving cryopreservation methods. By developing aqueous vitrification solutions with higher glass transition temperatures, researchers may be able to better protect organs from structural damage during freezing.

This breakthrough has implications beyond organ transplants. Improved preservation techniques could support wildlife and biodiversity conservation, enhance vaccine storage, and help reduce food waste.
