The Nodal family of signaling molecules includes critical intercellular regulators of early vertebrate development. In a recent issue of Nature, maternal transcripts encoding the zebrafish nodal squint were shown to be localized to the future organizer region by the four-cell stage, providing the earliest evidence of embryonic axis asymmetry in the zebrafish embryo.
信号分子的Nodal家族包括早期脊椎动物发育的关键细胞间调节因子。在最近一期的《自然》杂志上,编码斑马鱼Nodal斜视蛋白的母源转录本在四细胞期被定位到未来的组织者区域,这为斑马鱼胚胎中的胚胎轴不对称提供了最早的证据。
