In synMuv B mutants anterior intestinal cells are more delayed in compaction than posterior intestinal cells. (A-C) The position of open cells within a single embryo was monitored throughout development at 8E (A), 16E (B) and 20E (C) at both 20°C and 26°C. The anterior-to-posterior location of a cell was noted and that cell was recorded as having either an open or closed array. The percentage of cells with open arrays for each pair of sister cells was plotted to in an anterior-to-posterior directionality. The schematics to the left of the graphs represent the spatial organization of the intestinal cells at the 8E, 16E and comma stages.
