Two FGF receptor genes are differentially expressed in epithelial and mesenchymal tissues during limb formation and organogenesis in the mouse
Abstract
Fibroblast growth factors (FGFs) can influence the growth and differentiation of cultured cells derived from neuroectoderm, ectoderm or mesenchyme. The FGFs interact with a family of at least four closely related receptor tyrosine kinases that are products of individual genes. To investigate the role of FGFs in the growth and differentiation of embryonic tissues and to determine whether the individual FGF receptor genes might have specific functions, we compared the localization of mRNA for two FGF receptor genes, FGFR1 (the fig gene product) and FGFR2 (the bek gene product), during limb formation and organogenesis in mouse embryos (E9.5-E16.5). Although the two genes were coexpressed in some tissues, the differential expression of FGFR1 and FGFR2 in most embryonic tissues was striking. FGFR1 was expressed diffusely in mesenchyme of limb buds, somites and organ rudiments. In contrast, FGFR2 was expressed predominantly in the epithelial cells of embryonic skin and of developing organs. The differential expression of FGFR1 and FGFR2 in mesenchyme and epithelium respectively, suggests the receptor genes are independently regulated and that they mediate different functions of FGFs during development.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
