Expression of key patterning genes across early development.

<p>Expression levels in the 25 µm timeseries are normalized to the highest expression level at any time pioint. For slices with poor quality data (timepoint 4, slice 10; timepoint 6, slice 6; timepoint 7, slice 7; and timepoint 7, slice 8) data imputed from neighboring slices is shown. Expression levels for the 60 µm slice samples are normalized to the highest level in each embryo.
