Abstract
Intracellular signaling pathways are essential to establish embryonic patterning, including embryonic axis formation. Ectodermal patterning is also governed by a series of morphogens. Four ectodermal regions are thought to be controlled by morphogen gradients, but some perturbations are expected to occur during dynamic morphogenetic movement. Therefore, a mechanism to define areas precisely and reproducibly in embryos, including feedback regulation of signaling pathways, is necessary. In this review, we outline ectoderm pattern formation and signaling pathways involved in the establishment of the pre-placodal ectoderm (PPE). We also provide an example of feedback regulation of signaling pathways for robust formation of the PPE, showing the importance of this regulation.
细胞内信号通路对于建立胚胎形态(包括胚胎轴的形成)至关重要。外胚层模式也受一系列形态发生因子的控制。四个外胚层区域被认为是由形态发生梯度控制的,但在动态形态发生运动过程中预计会发生一些扰动。因此,有必要建立一种机制,包括信号通路的反馈调节,在胚胎中精确且可重复地定义区域。在这篇综述中,我们概述了外胚层模式的形成和建立前板层外胚层(PPE)所涉及的信号通路。我们还举例说明了信号通路的反馈调控对 PPE 的稳健形成所起的重要作用。
期刊介绍:
The Journal of Developmental Biology (ISSN 2221-3759) is an international, peer-reviewed, quick-refereeing, open access journal, which publishes reviews, research papers and communications on the development of multicellular organisms at the molecule, cell, tissue, organ and whole organism levels. Our aim is to encourage researchers to effortlessly publish their new findings or concepts rapidly in an open access medium, overseen by their peers. There is no restriction on the length of the papers; the full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Journal of Developmental Biology focuses on: -Development mechanisms and genetics -Cell differentiation -Embryonal development -Tissue/organism growth -Metamorphosis and regeneration of the organisms. It involves many biological fields, such as Molecular biology, Genetics, Physiology, Cell biology, Anatomy, Embryology, Cancer research, Neurobiology, Immunology, Ecology, Evolutionary biology.
