Fig. 1. Cell morphologies in wing discs. Pseudo-colorized confocal sections of a
wing disc (110 hours AED) stained with
-spectrin illustrates cell
morphologies in the peripodial epithelium (PE) and disc proper (DP). Disc
oriented with anterior leftwards, dorsal upwards. Broken white lines mark the
orientations of optical cross-section and longitudinal section. Red, squamous
peripodial epithelium (sPE); yellow, cuboidal cells of the margin in the
peripodial epithelium (mPE) and disc proper (mDP); blue, columnar cells of the
disc proper (cDP). (A) Confocal image of the PE; (B) longitudinal section; (C)
confocal section in plane of the DP (5 µm below PE); (D) cross-section.
Scale bar: 50 µm.
