Figure 3


Fig. 3. Distribution of histone H3K4me3 in S. ocellaris embryonic germ nuclei at the resting stage. (A-C) Chromosome DAPI staining, (A'-C') indirect immunolabelling with anti-H3K4me3 antibody and (A"-C") superimposed images where antibody staining is in red. (A-C) S. ocellaris germ nuclei (A) prior to, (B) during and (C) after the occurrence of Xp chromosome elimination. In all cases only four chromosomes of the complement are highly labelled (A'-C' and A"-C"). (A-A") Somatic nuclei exhibit some H3K4me3 labelling at discrete nuclear sites (arrow). (B-B") A S. ocellaris germ nucleus undergoing elimination where it is seen that the Xp chromosome expelled from the nucleus (asterisk in B) is not stained (asterisks in B' and B"). Somatic chromosomes at mitosis are highly H3K4me3 labelled (arrow in B-B"). Bar, 10 µm.
