Description

According to the authors of the study, imaging such highly dynamic processes in the cell and in 3D poses major technical challenges in a complex cell monolayer due to cell-to-cell variations in thickness and temporal properties of protein transport. Previous imaging techniques were slow and suffered from poor z-localization/3D-tracking capability.
