Project description:Recently, microRNAs (miRNAs) have emerged as new players in the fine tuning of embryo development and implantation in mammals via posttranscriptional gene regulation mechanisms. Applying custom made multispecies arrays we aimed to analyze expression profile of microRNAs in peri-implantation porcine conceptuses/trophoblasts to identify their potential role at the maternal-fetal interface during the critical period of maternal recognition of pregnancy and implantation. miRNA expression profiles were analyzed in samples collected from embryos or trophoblast on Days 10, 11, 12, 16 and 20 of pregnancy. Each group was represented by five to nine samples.

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:Anaylsis differentially expressed genes of mouse peri-implanted uteri comparing pre-implantation uteri (Day2, Day3 and Day4) with post-implantation uteri (Day6, Day7 and Day8) by microassay. This study has built a meaningful basis for future investigation in elucidating the molecular nature of maternal-fetal interactions during pregnancy establishment and maintenance. Pre-implantation uteri VS. Post-implantation uteri. Three biological replicates of each experiments: pre-implantation uteri (Day2, Day3 and Day4): 234, 234①, 234②; 3 mixture of post-implantation uteri (Day6, Day7 and Day8): 678, 678①, 678②. Two hybridizations were performed by using a reverse fluorescence strategy (Cy3, Cy5) for each sample.

Project description:Supporting healthy pregnancy outcomes requires a comprehensive understanding of the cellular hierarchy and underlying molecular mechanisms during peri-implantation development. Here, we presented a single-cell transcriptome-wide view of the bovine peri-implantation embryo development at day 12, 14, 16 and 18, when most of the pregnancy failure occurs. We defined the development and dynamic progression of cellular composition and gene expression of embryonic disc, hypoblast, and trophoblast lineages during bovine peri-implantation development. Notably, the comprehensive transcriptomic mapping of trophoblast development revealed a previous unrecognized primitive trophoblast cell lineage that are responsible for pregnancy maintenance in bovine prior to the time when binucleate cell emerges. We analyzed novel markers for the cell lineage development during bovine early development. We also identified cell-cell communication signaling underling embryonic and extraembryonic cells interact to ensure proper early development in bovine. Collectively, our work provides foundational information to discover essential biological pathways underpinning bovine peri-implantation development and the molecular causes of the early pregnancy failure during this critical period.

Project description:Our ability to study early human post-implantation development remains highly limited due to the ethical and technical challenges associated with intrauterine development of the human embryo after implantation. Despite the great progress made on human blastoids or gastruloids, such elegant models do not constitute an integrated synthetic stem cell-derived embryoid models (SEMs) that includes all the key extra-embryonic tissues of the early pre-gastrulating implanted human conceptus (e.g. hypoblast, yolk-sac, trophoblasts, amnion and extraembryonic mesoderm), and thus, do not recapitulate post-implantation epiblast development within the context of these extra-embryonic compartments. Mouse naïve pluripotent stem cells (PSCs) have recently been shown to give rise to embryonic and extra-embryonic stem cells capable of self-assembling into post-gastrulation mouse SEMs, while bypassing the blastocyst-like stage, and eventually initiating organogenesis ex utero. Here, we implement critical adaptations to extend these finding in humans, using only genetically unmodified human naïve PSCs, circumventing the need for ectopic expression of lineage promoting transgenes. Such integrated human SEMs recapitulate all known compartments of early post-implantation stage human embryos, including epiblast, hypoblast, extra-embryonic mesoderm, and trophoblast surrounding the latter layers. The organized human SEMs recapitulate key hallmarks of post-implantation stage embryogenesis up to 13-14 days post-fertilization (dpf, Carnegie stage 6a), such as bilaminar disk formation, epiblast lumenogenesis, amniogenesis, anterior-posterior symmetry breaking, PGC specification, primary and secondary yolk sac formation, and extra-embryonic mesoderm expansion that defines a chorionic cavity and a connective stalk. This new platform constitutes a tractable stem cell-based model for experimentally interrogating previously inaccessible windows of human early peri- and post-implantation development.
