(d) Dimensions of microclusters in cell numbers with high and similar levels of HES5 in apical-basal axis (left panel) and dorso-ventral axis (right panel) at E9.5 (10 microclusters, 3 slices, 3 exps), E10.5 (10 microclusters, 9 slices, 3 exps) and E11.5 (10 microclusters, 3 slices, 3 exps). NS - no significant difference in one-way ANOVA p=0.46 (A-B), p=0.38 (D-V). Bars show mean ±SD.
