Fig. 3. In vivo comparison of IPL formation and sublamination in wild-type and
lak mutants. Time-lapse imaging of retinas in line 220 wild-type and
lakritz (lak) mutant backgrounds during IPL formation and
differentiation. Both IPL formation and sublamination are delayed in the
mutants. Each image is the z-projection of 3 µm confocal image
stacks. Dorsal retina is towards the top. All three animals shown here were
age-matched siblings, and were imaged concurrently. In all images, arrows
indicate location of the developing IPL. Opposing arrows at 82 (wild type) and
85 (lak2) hpf indicate location where sublamination is apparent. Note
that the IPL of lak2 becomes more organized with time. Movies showing
time-lapse recordings from additional wild-type and lak siblings are
