... -expressing cells were labeled by membrane-bound GFP, and the cell and ECM morphologies were examined after 24 hours, when cell shape changes would have been completed under normal conditions (cf. Fig. 5G-I ). Typically, we saw that the ball developed as an amorphous bulb without the ‘lip’, and the socket...

...-cadherin was closely correlated with a dynamic cell shape change associated with epithelial reorganization during fusion. In esg mutants, tip cells of a subset of the tracheal branch failed to accumulate D E-cadherin and such branches did not fuse but became hyperactive in motility. This phenotype...
