Comparison of the Notch and Su(H) mutant clones with and without expression of ArmS10. Confocal images of third instar wings discs with clones of cells induced between 72–96 h AEL mutant for both Notch55e11 (A and C) or Su(H)Δ47 (B and D), without and with ArmS10 as indicated (labelled in green). This late generated Su(H)Δ47 clones of cells already have apoptotic cells on the basal side (white arrows), which are not seen in the Notch55e11. Expression of ArmS10 in these cells increases the size of the Su(H) mutant clones, alters their appearance, and reduces, but does not eliminate, the number of apoptotic cells in the basal region or the interdispersion of the clones. In the Notch mutant clones, the expression of ArmS10 increases the size of them and there are fewer (probably due to the coalescence of them) Technical details of the images as in Figure 2 with the small insets at the corners of each image are low magnification pictures of the discs shown which act as a reference. The complete z-stack of (B) and (D) can be found as Videos S4 and S5. Scale bar in (D2), 20 µm. (9.62 MB TIF)
