腭裂是人类常见的先天性出生缺陷。在哺乳动物中,腭组织可分为前部骨性硬腭和后部肌肉性软腭,它们在咬合、言语或吞咽方面具有特殊功能。上颚发育的调节似乎是上颚前部和后部区域独特的信号传导和遗传网络的结果。这些区域特异性基因表达的发育和维持对于正常的味觉发育至关重要。许多转录因子和信号通路现在被认为是前部特异性的(例如,Msx1、Bmp4、Bmp2、Shh、Spry2、Fgf10、Fgf7 和 Shox2)或后部特异性的(例如,Meox2、Tbx22 和 Barx1)。局部表达和功能清楚地强调了分子水平上腭内区域模式和分化的重要性。在这里,我们回顾这些分子途径和网络如何调节次级腭的前后模式和发育。我们假设前腭在建立次级腭的发育过程中充当信号中心。
Cleft palate is a common congenital birth defect in humans. In mammals, the palatal tissue can be distinguished into anterior bony hard palate and posterior muscular soft palate that have specialized functions in occlusion, speech or swallowing. Regulation of palate development appears to be the result of distinct signaling and genetic networks in the anterior and posterior regions of the palate. Development and maintenance of expression of these region-specific genes is crucial for normal palate development. Numerous transcription factors and signaling pathways are now recognized as either anterior- (e.g., Msx1, Bmp4, Bmp2, Shh, Spry2, Fgf10, Fgf7, and Shox2) or posterior-specific (e.g., Meox2, Tbx22, and Barx1). Localized expression and function clearly highlight the importance of regional patterning and differentiation within the palate at the molecular level. Here, we review how these molecular pathways and networks regulate the anterior–posterior patterning and development of secondary palate. We hypothesize that the anterior palate acts as a signaling center in setting up development of the secondary palate.
