“…Each plot is colored according to the Z score of the expression value amnion. 60 Moreover, Zhang et al recently reported that a part of the extraembryonic mesoderm gives rise to cardiomyocytes and serosal mesothelial cell types. 61 These cells may be considered comparable with iASCs in avians, although the route of entrance into the developing heart appears to be different between arterial and venous poles possibly due to topological differences in the position of the extraembryonic/intraembryonic boundary.…”

Background:The somatopleure serves as the primordium of the amnion, an extraembryonic membrane surrounding the embryo. Recently, we have reported that amniogenic somatopleural cells (ASCs) not only form the amnion but also migrate into the embryo and differentiate into cardiomyocytes and vascular endothelial cells. However, detailed differentiation processes and final distributions of these intra-embryonic amniogenic somatopleural cells (hereafter referred to as iASCs) remain largely unknown.Results: By quail-chick chimera analysis, we here show that iASCs differentiate into various cell types including cardiomyocytes, smooth muscle cells, cardiac interstitial cells, and vascular endothelial cells. In the pharyngeal region, they distribute selectively into the thyroid gland and differentiate into vascular endothelial cells to form intra-thyroid vasculature.Explant culture experiments indicated sequential requirement of FGF and VEGF signaling for endothelial differentiation of iASCs. Single-cell transcriptome analysis further revealed heterogeneity and the presence of hemangioblast-like cell population within ASCs, with a switch from FGF to VEGF receptor gene expression. Conclusion:The present study demonstrates novel roles of amniogenic somatopleural cells especially in heart and thyroid development. It will provide a novel clue for understanding the cardiovascular development of amniotes from embryological and evolutionary perspectives.

“…In both insects and amniotes, by the onset of gastrulation there are multiple early genetic markers for the presumptive serosa/chorion. These include Tc-zen1, Tc-zen2 and Tc-hnt for Tribolium [52] and Cdx2, Elf5 and Esrrb in Mus [53,54] (table 2). Upstream regulation of the presumptive insect serosa requires a subset of axial patterning determinants for anterior and dorsal regions of the blastoderm (figure 2, e.g.…”

“…In other cases, insect orthologues hold promise as a novel line of evidence in selecting new candidate genes for research into the amniote amnion (box 1). Transcriptomic datasets for the amnion have been generated for Mus [53,54] and Homo [74]. Moreover, single-cell RNA-seq datasets for gastrulating embryos of mouse [78,79] and human [75] are available.…”

“…Furthermore, changes in GATA3 expression are associated with changes in BMP and FGF signalling in other vertebrate tissues [88,89], and both signalling pathways are required for correct amnion development in Tribolium [38,90]. BMP signalling has been shown to be functionally important for amnion development in Mus ( [53,91,92], and see below), but not FGF signalling. This points to a common regulatory network (via GATA3 and BMP signalling) for amnion formation in insects and amniotes.…”

“…As mentioned above, the highly conserved BMP pathway (table 2 [101]) is crucial for both patterning and early amnion morphogenesis in amniotes and insects. Disrupting BMP signalling in Mus, via genetic deletion of the ligand Bmp2 or the cytoplasmic effector Smad5, resulted in defects in amnion/chorion closure, with subsequent malformations in heart development [53,91,92]. In both cases, the knockout mouse embryos developed until gastrulation, anteriorward Box 1.…”

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’.

The British Society for Developmental Biology Autumn Meeting, held in Oxford in September 2018, was the third in a series of international workshops which have been focussed on development at the extraembryonic-embryonic interface. This workshop, entitled “Embryonic-Extraembryonic Interactions: from Genetics to Environment” built on the two previous workshops held in 2011 (Leuven, Belgium) and 2015 (Göttingen, Germany). This workshop brought together researchers utilising a diverse range of organisms (including both vertebrate and invertebrate species) and a range of experimental approaches to answer core questions in developmental biology. This meeting report highlights some of the major themes emerging from the workshop including an evolutionary perspective as well as recent advances that have been made through the adoption of emerging techniques and technologies.

Correction: Amniotic ectoderm expansion in mouse occurs via distinct modes and requires SMAD5-mediated signalling (doi: 10.1242/dev.157222)

Abstract: On p.1, the sentence should read 'This causes amnion-chorion separation and results in three cavities at E7.5: the amniotic and ectoplacental cavities, and the de novo-derived exocoelomic (visceral yolk sac) cavity.'
