成纤维细胞生长因子 (FGF) 分别由 FGF10 和 FGF9 介导的上皮和间质信号传导控制胚胎发育过程中的盲肠形成。特别是,间充质 FGF10 通过 FGFR2b 向上皮细胞发出信号,诱导上皮盲肠祖细胞增殖。然而控制间充质 FGF10 信号传导的精确上游机制尚不清楚。 Fgf9 和 Pitx2(一种编码同源盒转录因子的基因)的完全缺失都会导致盲肠发育不全。在此,我们使用小鼠遗传方法来确定上皮和/或间充质组织区室在此过程中的精确贡献。使用肠道上皮和/或间充质中组织区室特异性 Fgf9 与 Pitx2 功能丧失方法,我们确定 FGF9 通过 Pitx2 向间充质发出信号,诱导间充质 Fgf10 表达,进而导致上皮盲肠芽形成。
Fibroblast growth factor (FGF) signaling to the epithelium and mesenchyme mediated by FGF10 and FGF9, respectively, controls cecal formation during embryonic development. In particular, mesenchymal FGF10 signals to the epithelium via FGFR2b to induce epithelial cecal progenitor cell proliferation. Yet the precise upstream mechanisms controlling mesenchymal FGF10 signaling are unknown. Complete deletion of Fgf9 as well as of Pitx2, a gene encoding a homeobox transcription factor, both lead to cecal agenesis. Herein, we used mouse genetic approaches to determine the precise contribution of the epithelium and/or mesenchyme tissue compartments in this process. Using tissue compartment specific Fgf9 versus Pitx2 loss of function approaches in the gut epithelium and/or mesenchyme, we determined that FGF9 signals to the mesenchyme via Pitx2 to induce mesenchymal Fgf10 expression, which in turn leads to epithelial cecal bud formation.
