Bio-inspired hydrogel protects the heart from post-op adhesions

A hydrogel that forms a barrier to keep heart tissue from adhering to surrounding tissue after surgery was developed and successfully tested in rodents by a team of University of California San Diego researchers. The team of engineers, scientists and physicians also conducted a pilot study on porcine hearts, with promising results.

They describe their work in the June 18, 2021 issue of Nature Communications.
