Project description:Our understanding of human early development is severely hampered by limited access to embryonic tissues. Due to their close evolutionary relationship with humans, non-human primates (NHPs) are often used as surrogates to understand human development but currently suffer from a lack of in vivo datasets, especially from gastrulation to early organogenesis during which the major embryonic cell types are dynamically specified. To fill this gap, we have collected six Carnegie stage (CS) 8-CS11 cynomolgus monkey embryos and performed in-depth transcriptome analyses of 56,636 single cells. Our analyses reveal transcriptomic features of major peri-gastrulation cell types, which help shed light on morphogenetic events including primitive streak (PS) development, somitogenesis, gut tube formation, neural tube patterning, and neural crest regionalization in primates. In addition, comparative analyses with mouse embryos and human embryoids uncover conserved and divergent features of peri-gastrulation development across species, e.g. species-specific dependency on Hippo signaling during presomitic mesoderm differentiation, and provide an initial assessment of relevant stem cell models of human early organogenesis. This comprehensive single-cell transcriptome atlas not only fills the knowledge gap in the NHP research field but also serves as an invaluable resource for understanding human embryogenesis and developmental disorders.

In addition, comparative analyses with mouse embryos and human embryoids uncovered conserved and divergent features of perigastrulation development across species-for example, species-specific dependency on Hippo signalling during presomitic mesoderm differentiation-and provide an initial assessment of relevant stem cell models of human early organogenesis. This comprehensive single-cell transcriptome atlas not only fills the knowledge gap in the nonhuman primate research field but also serves as an invaluable resource for understanding human embryogenesis and developmental disorders.

Project description:Establishment of the mammalian body plan occurs shortly after the embryo implants into the maternal uterus, and our understanding of post-implantation developmental processes remains limited. While methods for in vitro culture of pre- and peri-implantation mouse embryos are routinely utilized, approaches for robust culture of post-implantation embryos from egg cylinder stages until advanced organogenesis remain to be established. We develop herein highly stable ex utero post-implantation mouse embryo culture platforms, that enable appropriate development of embryos before gastrulation (E5.5) until the hind limb formation stage (E11). Late gastrulating embryos (E7.5) are grown in 3D rotating bottles settings, while extended culture from pre-gastrulation stages (E5.5 or E6.5) requires a combination of novel static and rotating bottle culture protocols. Histological, molecular, and single cell RNA-seq analysis validate that the ex utero developed embryos recapitulate precisely in utero development. This culture system is amenable to introducing a variety of embryonic perturbations and micro-manipulations that can be followed ex utero for up to 6 days. Establishment of a system to robustly grow normal mouse embryos ex utero from pre-gastrulation to advanced organogenesis represents a valuable tool to investigate post-implantation embryogenesis, eliminating the uterine barrier to mechanistically interrogate morphogenesis and tissue specification in mammals.

Project description:Gastrulation and early organogenesis are remarkable processes of early embryonic development. Our previous study showed that deletion of DYT6 gene product THAP1 leads to embryonic lethality at the stage of gastrulation and early organogenesis. However, the function of THAP1 in regulating gene expression, as well as its role in regulating embryo gastrulation and early organogenesis are not well characterized. In this study, we used different in vitro and in vivo models to characterize the function of THAP1 in regulating gene expression and in controlling embryonic development, which could help us to understand pathogenesis of THAP1-associated disorders and provide data to characterize the transcription regulation of gastrulation of murine embryo.
