躯干神经嵴细胞在发育中的脊椎动物胚胎内沿着特征路径快速迁移。适当的躯干神经嵴细胞迁移对于大部分周围神经系统、黑素细胞和肾上腺髓质的形态发生是必要的。许多分子有助于引导躯干神经嵴细胞在整个早期胚胎中迁移。在这里,我们通过体外趋化性测定和通过 DN-erbB 受体的体内沉默证明营养因子 NRG1 是一种化学引诱剂。有趣的是,我们还观察到迁移反应的变化与 NRG1 对躯干神经嵴速度的趋化作用一致。 NRG1 是一种躯干神经嵴细胞趋化剂和趋化分子。
Trunk neural crest cells migrate rapidly along characteristic pathways within the developing vertebrate embryo. Proper trunk neural crest cell migration is necessary for the morphogenesis of much of the peripheral nervous system, melanocytes, and the adrenal medulla. Numerous molecules help guide trunk neural crest cell migration throughout the early embryo. Here, we show that the trophic factor NRG1 is a chemoattractant through in vitro chemotaxis assays and in vivo silencing via a DN-erbB receptor. Interestingly, we also observed changes in migratory responses consistent with a chemokinetic effect of NRG1 in trunk neural crest velocity. NRG1 is a trunk neural crest cell chemoattractant and chemokinetic molecule.
