nervous system
• at E14.5, cells expressing lacZ are found across the dorsal and posterior borders of the thalamus expanding into the epithalamus and pretectum
• ectopic lacZ expressing cells from the thalamus are mainly found in the lateral habenular nuclei and anterior part of the pretectum at E18.5
• at E10.5 the thalamus is smaller in the mediolateral dimension and larger in the ventrodorsal dimension
• thalamus morphology is severely disrupted after E14.5

• following tamoxifen treatment mild defects in thalamus morphology are seen in some mutants with high levels of recombination but for the most part defects in establishment of dorsal and posterior thalamic boundaries seen in null mice are not seen
• this result and chimera experiments suggest that the function of Gbx2 is cell nonautonomous
