Fig. 7. Eye imaginal discs labelled with CM1 antiserum. (A) hid/hid. (B) hid/+. (C) GMRDIAP1 /GMRDIAP1. (D) GMRDIAP1/GMRp35. (E) N^l1-Nts1, 31.5°C for 4 hours. (F-H) egfr^f24 clones in hid/hid larva. (F) ArmlacZ. Arrows indicate the small clones that result when Minutes are not used. (G) CM1 labelling. (H) F,G combined, showing complete absence of apoptosis from clones (arrows). (I-L) egfr^f24 clones in GMRDIAP1 larva. (I) ArmlacZ. (J) CM1 labelling. (K) ELAV labelling of differentiating photoreceptors. (L) Combination of I-K showing apoptosis of egfr mutant cells. (M-P) egfr^f24 clones in GMRp35 larva. (M) ArmlacZ. (N) CM1 labelling. (O) ELAV labelling of differentiating photoreceptors. (P)M-O combined. Contrast morphology of CM1-labelled cells with the apoptotic cells in J. Note reduced CM1 labelling of differentiating egfr^f24 photoreceptors (arrows in N,P).
