心脏神经嵴起源于后脑尾部,迁移到心脏,并有助于心脏流出道和心室的分隔,这是神经嵴亚群所特有的能力。在这里,我们使用FoxD3神经嵴增强子分离心脏神经嵴细胞的纯群体进行转录组分析。这导致了转录因子、信号受体/配体和细胞粘附分子在早期迁移的心脏神经嵴上调的鉴定。然后我们研究了MafB,发现它作为Sox10表达的调节剂在心脏神经嵴特异性地起作用。我们的研究结果不仅揭示了早期迁移的心脏神经嵴细胞的全基因组图谱,而且还提供了使心脏神经嵴独特的分子见解。
The cardiac neural crest originates in the caudal hindbrain, migrates to the heart, and contributes to septation of the cardiac outflow tract and ventricles, an ability unique to this neural crest subpopulation. Here we have used a FoxD3 neural crest enhancer to isolate a pure population of cardiac neural crest cells for transcriptome analysis. This has led to the identification of transcription factors, signaling receptors/ligands, and cell adhesion molecules upregulated in the early migrating cardiac neural crest. We thenW MafB, and found that it functions as a regulator of Sox10 expression specifically in the cardiac neural crest. Our results not only reveal the genome-wide profile of early migrating cardiac neural crest cells, but also provide molecular insight into what makes the cardiac neural crest unique.
