Summary
edit
| Description | Figure 1. A histone modification corresponding to a transcriptionally competent chromatin structure is present in all cells of the early embryo, but absent from Z2 and Z3. Fixed, whole-mount embryos were stained with anti-H3methK4 (green), anti-PGL-1 (blue; marking the germ lineage), and counter-stained with DAPI (red). (A) H3dimethK4 is equally present in both AB and P1 (arrow) of 2-cell embryos, and persists in the germline blastomeres through (B) P2, (C) P3, and (D) P4. However, a specific chromatin reorganization occurs in the primordial germ cells Z2 and Z3 (enlarged in insets), which are now the only cells to lose both H3methK4 (E) and H4acetylK8 (F). Bar = 5 μm.
