Project description:Successful establishment and maintenance of pregnancy can be attained only through optimum conceptus-maternal cross talk. Despite significant progress in our understanding of the temporal changes in the transcriptome of the uterine endometrium, we have only a rudimentary knowledge of the genes and pathways governing growth and development of the bovine conceptus. In particular, very little information exists for the posthatchingembryo and elongating conceptus. This period of development is arguably the most important, as approximately 40% of all embryonic loss occurs between Days 8 and 17 of pregnancy in cattle. Here, we describe the global transcriptome profile of the bovine conceptus at five key stages of its pre- and peri-implantation growth (Days 7, 10, 13, 16, and 19) using state-of-the-art RNA sequencing techniques. More than 287 million reads were generated at the five stages, and more than 22?700 unique transcripts were detected. Analysis of variance followed by self-organizing maps identified differentially regulated (P < 0.05) genes organized in nine gene clusters forming a sequential transcript dynamics across these developmental stages. Of particular interest, genes in clusters 3 (n = 236) and 6 (n = 1409) were significantly up-regulated on Days 16 and 19, suggesting a role in maternal recognition and initiation of implantation. This transcriptome analysis of the bovine conceptus will provide a blueprint of the dynamic changes in gene expression occurring during maternal recognition and implantation and will complement existing knowledge of the temporal changes in the endometrial transcriptome, thus facilitating a better understanding of conceptus-maternal cross talk during the peri-implantation period of pregnancy. mRNA-seq study of bovine conceptuses at 5 stages of development (days 7, 10, 13, 16 and 19) post fertilization.

Project description:Conceptus implantation to the uterine endometrium is required for pregnancy establishment, during which non-invasive trophoblasts attach and adhere to the uterine endometrium or invasive trophoblasts invade into the uterine stroma, followed by placental formation in most mammalian species. During peri-implantation period, conceptuses must communicate with the uterine endometrium if they are to survive and proceed to attachment to the uterine epithelium. Despite numerous studies performed on the bovine species, molecular mechanisms associated with their attachment processes, particularly the initial attachment to the endometrial epithelium, have not been well characterized.

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.
