Fig. 2. Glial development followed by time-lapse. (A) Pupa preparation for
time-lapse. Red lines indicate the path of puparium case dissection. The
operculum is opened (left panel, straight line), and the puparium case over
the wing is removed (mid and right panel, dashed lines). Left and mid panels
are dorsal views; right panel is a lateral view. Anterior is to the top. W,
wing. (B) repo-actinGFP: time-lapse images of a GPI showing dynamic
cell shape and filopodia reorganisation (arrowheads). (C) Time-lapse images
showing repo-ncGFP (nuclear and cytoplasmic GFP) labelling (see Movie
1 in supplementary material). Symbols as in
Fig. 1B. Brackets indicate the
glial cells originating from L3 gliogenic sensory organs. Arrows show the L1
front of migration. Arrowheads indicate the positions of L3.3 glial nuclei.
Scale bars: 20 µm (B); 70 µm (C).
