经典的Wnt/β-catenin通路是多种发育过程的重要组成部分。为了研究该途径在外胚层中在面部形态发生中的作用,我们使用新型外胚层特异性Cre重组酶转基因系产生了条件性β-连环蛋白小鼠突变体。我们的研究结果表明,消除或稳定β-连环蛋白在胚胎外胚层引起面部形态的显着变化。伴随着Fgf 8和Shh表达的改变,这些关键分子建立了对面部图案至关重要的信号中心,额鼻外胚层区(FEZ)。这些数据表明,外胚层内的Wnt/β-catenin信号传导对面部发育至关重要,并进一步表明该途径是在进化过程中产生脊椎动物不同面部形状的重要机制。
The canonical Wnt/β-catenin pathway is an essential component of multiple developmental processes. To investigate the role of this pathway in the ectoderm during facial morphogenesis, we generated conditional β-catenin mouse mutants using a novel ectoderm-specific Cre recombinase transgenic line. Our results demonstrate that ablating or stabilizing β-catenin in the embryonic ectoderm causes dramatic changes in facial morphology. There are accompanying alterations in the expression of Fgf8 and Shh, key molecules that establish a signaling center critical for facial patterning, the frontonasal ectodermal zone (FEZ). These data indicate that Wnt/β-catenin signaling within the ectoderm is critical for facial development and further suggest that this pathway is an important mechanism for generating the diverse facial shapes of vertebrates during evolution.
