Hidden cell networks emerge in 3D as new nanoscopy tracks living bridges
A new nanoscopy technique developed at The Australian National University (ANU) has uncovered hidden networks used for communication between cells, opening new ways to understand human diseases. Described in an article published in Nature Communications, the method allows researchers to observe how living cells interact with their environment over several days, revealing three-dimensional behaviors that were previously invisible to conventional microscopes.
