Scientists created a special testing system to study how different conditions affect the thin membranes that surround babies before they are born during a type of surgery called fetoscopy.
They tested the membranes by blowing air at different pressures, humidity levels, and temperatures while measuring how stiff or weak they became.
The results showed that low humidity made the membranes brittle and caused cell damage, while high humidity helped keep them strong, making this new model a useful tool to understand how surgery impacts these membranes.
