โœฆ Synopsis

Fibroblast growth factors may play an important role in the differential growth of the skull, brain, and facial prominences. In order to understand the role of FGFs in vivo, we have analyzed the competency of head mesenchyme to respond to FGFs via expression of the high affinity receptors FGFR1, 2, and 3. Receptor transcripts, especially those of FGFR2 and FGFR3, were localized to specific regions of the head. We raise the possibilities of particular receptor-ligand combinations and the possible functions of these interactions in the morphogenesis of the head, face, and brain. Finally, we discuss the relationship between FGF receptor expression in the chicken and the phenotypes of FGF receptor mutations in humans. Dev.

## Abstract Fibroblast growth factors (FGFs) are important regulators of retinal development and survival. We examined the expression and distribution of FGF9 and its preferred receptors FGFR2IIIc and FGFR3IIIc in this tissue. FGF9 transcripts in whole rat retina were detected by RTโ€PCR but were no

The mapping of the achondroplasia locus to the short arm of chromosome 4 and the subsequent identification of a recurrent missense mutation (G380R) in the fibroblast growth factor receptor 3 (FGFR-3) gene has been followed by the detection of common FGFR-3 mutations in two clinically related disorde
