成纤维细胞生长因子在内耳发育中起重要作用。先前的研究表明,小鼠Fgf16在耳杯和小泡发育阶段不对称表达,这表明Fgf16在调节或响应前后轴信号中起作用。在这里,我们研究了胚胎发育过程中耳部Fgf16的表达,并在发育中的嵴和耳蜗管侧壁的一些细胞中发现了转录本。为了确定Fgf16的功能并追踪表达Fgf16的细胞的命运,我们生成了一个Fgf16IRESCre等位基因。我们发现Fgf16在内耳发育中并没有独特的作用,而且Fgf16谱系遍布于三个嵴、部分半规管和耳蜗螺旋突上皮细胞中。该菌株可用于这些组织的基因消融。
Fibroblast growth factors play important roles in inner ear development. Previous studies showed that mouse Fgf16 is expressed asymmetrically during the otic cup and vesicle stages of development, suggesting roles in regulating or responding to anteroposterior axial cues. Here, we studied otic Fgf16 expression throughout embryonic development and found transcripts in the developing cristae and in a few cells in the lateral wall of the cochlear duct. To determine the otic function of Fgf16 and to follow the fate of Fgf16-expressing cells, we generated an Fgf16IRESCre allele. We show that Fgf16 does not have a unique role in inner ear development and that the Fgf16 lineage is found throughout the three cristae, in portions of the semicircular canal ducts, and in the cochlear spiral prominence epithelial cells. This strain will be useful for gene ablations in these tissues.
