Gallus gallus Control Versus SU5402, LY294002 or U0126 Treated Preingression Epiblast from Gastrula Stage Embryos

ABSTRACT: Transcriptional profiling of the preingression epiblast versus lateral epiblast, of preingression epiblast from control embryos treated with the DMSO carrier vehicle (0.5%) versus embryos treated with SU5402, U0126 or LY294002. Embryos were stages 5-6 at time of tissue isolation. The preingression epiblast (E2 region) is the region of epiblast just lateral to the primitive streak. Lateral epiblast is the E3 region. Two condition experiment. Samples for each condition isolated from at least 30 embryos. The experiments used isolated preingression epiblast, which is defined as the region of epiblast adjacent to the primitive streak that will ingress through the primitive streak. Preingression epiblast was isolated by microdissection using tungsten needles from control embryos or embryos treated with SU5402, U0126 or LY294002.

Single Cell Expression Profiling Resolves the Transcriptional Programs of Early Mesoderm Diversification

Project description:We analyzed 1,205 cells from the epiblast and nascent mesoderm of gastrulating mouse embryos by single cell RNA-seq, representing the first transcriptome-wide in vivo view of mammalian gastrulation. Based on the distribution of key marker genes and their spatiotemporal expression patterns within the embryo, we identified 10 cell clusters corresponding to the epiblast and developing mesodermal populations. This enabled us to explore the global gene expression dynamics associated with the induction of Brachyury, anterior-posterior patterning of the primitive streak and the earliest stages of blood development.

Single cell RNA seq of mouse embryos from E7.0, E7.25 and E7.5

Project description:During mouse gastrulation, the formation of germ layers proceeds concurrently with the transition pluripotency state and the allocation of the multipotent epiblast cells to the germ layer derivatives. Lineage analysis and fate-mapping studies have revealed that groups of cells in different regions of the epiblast and the primitive streak of the gastrulating embryo are allocated to separate progenitors of the ectoderm, mesoderm and endoderm lineages three germ layers with descendants of each progenitor contributing to specific types of germ layer derivatives. Spatiotemporal transcriptomic analysis of the epiblast cell population has inferred that besides the allocation of the epiblast cells to progenitors of germ layers, a population of putative mesendoderm progenitors may be present in the gastrulating embryos.

Patterning and gastrulation defects caused by the tw18 lethal are due to loss of Ppp2r1a

Project description:The mouse t haplotype, a variant 20 cM genomic region on Chromosome 17, harbors sixteen embryonic control genes identified by recessive lethal mutations isolated from wild mouse populations. Due to technical constraints so far only one of these, the tw5 lethal has been cloned and molecularly characterized. Here we report the molecular isolation of the tw18 lethal. Embryos carrying the tw18 lethal die from major gastrulation defects commencing with primitive streak formation at E6.5. We have used transcriptome and marker gene analyses to describe the molecular etiology of the tw18 phenotype. We show that both WNT and Nodal signal transduction are impaired in the mutant epiblast causing embryonic patterning defects and failure of primitive streak and mesoderm formation. We have used a candidate gene approach, gene knockout by homologous recombination and genetic rescue to identify the gene causing the tw18 phenotype as Ppp2r1a, encoding the PP2A scaffolding subunit PR65. Our work highlights the importance of phosphatase 2A in embryonic patterning, primitive streak formation, gastrulation, and mesoderm formation downstream of WNT and Nodal signaling.
