Local retinoid signaling coordinates forebrain and facial morphogenesis by maintaining FGF8 and SHH

Abstract excerpt

Correlations between facial anomalies and brain defects are well characterized throughout the clinical literature, yet a developmental basis for this association has not been identified. We demonstrate that the frontonasal process, which gives rise to the mid- and upper face, and the forebrain are linked early in their morphogenesis by a local retinoid signaling event that maintains the expression of key...
