有趣的是，羊膜和浆膜/绒毛膜，这两种胚胎外（EE）组织是脊椎动物（哺乳动物，鸟类和爬行动物）的特征，也在昆虫中独立进化。在这篇综述中，我们提供了第一个详细的，宏观进化比较EE的发展和组织生物学在这些动物群体。一些共性代表了保护胚胎（环境攻击、病原体风险）和支持其发育的共同挑战的独立解决方案，包括细胞特性（例如多倍性）和生理功能之间的明确联系。进一步的相似之处包括发育特征，如早期分离的浆膜/绒毛膜相比，后来，渐进分化的羊膜和羊膜腔的形成从浆膜羊膜褶皱作为一个广泛的形态发生模式跨物种。我们还讨论了共同的发展作用orthostransplantation转录因子和BMP信号在EE组织的昆虫和昆虫，EE和心脏组织之间，我们的全球和组织特异性基因表达的新资源的探索支持。这突出了从这些动物群体中可以推断出一般发育原则和保护组织特征的程度，强调了广泛比较研究的价值，以揭示微妙的发育策略并回答跨物种常见的问题。这篇文章是“胚外组织：探索动物王国的概念，定义和功能”主题的一部分。
It is fascinating that the amnion and serosa/chorion, two extraembryonic (EE) tissues that are characteristic of the amniote vertebrates (mammals, birds and reptiles), have also independently evolved in insects. In this review, we offer the first detailed, macroevolutionary comparison of EE development and tissue biology across these animal groups. Some commonalities represent independent solutions to shared challenges for protecting the embryo (environmental assaults, risk of pathogens) and supporting its development, including clear links between cellular properties (e.g. polyploidy) and physiological function. Further parallels encompass developmental features such as the early segregation of the serosa/chorion compared to later, progressive differentiation of the amnion and formation of the amniotic cavity from serosal–amniotic folds as a widespread morphogenetic mode across species. We also discuss common developmental roles for orthologous transcription factors and BMP signalling in EE tissues of amniotes and insects, and between EE and cardiac tissues, supported by our exploration of new resources for global and tissue-specific gene expression. This highlights the degree to which general developmental principles and protective tissue features can be deduced from each of these animal groups, emphasizing the value of broad comparative studies to reveal subtle developmental strategies and answer questions that are common across species. This article is part of the theme issue ‘Extraembryonic tissues: exploring concepts, definitions and functions across the animal kingdom’.
