Dorsal-ventral patterning defects in the eye of BF-1-deficient mice associated with a restricted loss of shh expression.

Abstract excerpt

Brain factor 1 (BF-1) is a winged-helix transcription factor with restricted expression in the anterior optic vesicle and in the telencephalic neuroepithelium of the neural tube. We have previously found that targeted disruption of the BF-1 gene results in hypoplasia of the cerebral hemispheres, which is more severe in structures derived from the ventral telencephalon. Here we show that the loss of BF-1 leads to...
