Notching the hive
During Drosophila cellularization, cell membranes grow basally until they encapsulate individual nuclei from the syncytium. At the same time, Notch accumulates in the junctions of growing membranes, and signalling initiates when membranes have only partially grown to define a stripe of cells that give rise to the ventral nerve cord. Image captured using Structured Illumination Microscopy (SIM) of a cellularizing Drosophila embryo stained for Notch (yellow), E-Cadherin (magenta) and F-actin (cyan).
