Wing imaginal discs with clones as shown in Figure 2. Confocal images of third instar wings discs with MARCM clones (labelled in green) of Notch mutant cells (A and A1), of Notch mutant cells that overexpress ArmS10 (B and B1), and of Notch mutant cells that overexpress ArmS10 and CeN (C and C1), induced at 48–72 h (A–C) or 72–96 h AEL (A1–C1). Notice that the clones expressing ArmS10 are much larger and display a rounded appearance. The red channel shows Scribble, the clones are labelled in green. This image corresponds to the discs shown in the inset of Figure 2 and allows a magnified visualization of the distribution and shape of the clones in the imaginal discs. Scale bar in (C1), 100 µm.
