Transcription factor domains in the developing hypothalamus. (A-P) RNA in situ hybridization on E12.5 transverse sections. The ventral diencephalon of selected sections along the anterior-posterior axis is shown. Hyp, hypothalamus; Mb, midbrain. (Q) Summary of gene expression domains. Note that only gene expression domains in the hypothalamus are indicated in the schematic, and thalamic gene expression is not indicated. Scale bar: 200 μm.
