Figure 2. Patterned cell state properties in the developing pupal wing of Drosophila.
(A–D') Cell state patterns at 22 hr and 31 hr after puparium formation (hAPF). (A–A') Color-coded cell area. (B–B') Color-coded cell elongation. The magnitude of cell elongation corresponds to the norm of the cell elongation nematic tensor. (C–C'') Coarse-grained pattern of cell elongation nematics and (C'') cell elongation nematics represented as bars on each individual cell. The wing was divided into adjacent square-grid elements of 33x33 microns in which cell elongation nematics were averaged. (D–D') Color-coded representation of the cell neighbor number. (E) Time evolution of the average cell area in different regions of interest: wing blade (Figure 1B), veins (Figure 1E), and inter-vein regions. (F) Time evolution of the average cell elongation magnitude in the blade, veins and inter-vein regions. Scale bar: 50 microns.
