Multi-axial self-organisation properties of mouse embryonic stem cells into gastruloids [individual]

Project description:Gastruloids, small aggregates of murine Embryonic Stem (ES) cells stimulated to undergo gastrulation-like symmetry breaking events in vitro (van den Brink, S. C. et al. 2014, Simunovic, M. & Brivanlou, A. H 2017). Analysis of the transcriptional profiles from pools of gastruloids collected at different time-points after aggregation (AA) revealed that gastruloids are capable of organizing an axially integrated post-occipital pattern of neural, mesodermal and endodermal derivatives that mimics that of the embryo in terms of gene expression. To test the homogeneity and reproducibility of the transcriptional programs uncovered by our bulked RNAseq experiments, we performed RNAseq analysis of individual gastruloids collected at different time-points AA (10 biological replicates per time-point). Our results indicates that the transcriptional profiles of gastruloid were highly reproducible at each time points and that each gastruloid implement the full diversity of transcriptional programs detected in our bulked RNAseq experiments.

Multi-axial self-organisation properties of mouse embryonic stem cells into gastruloids [E6.5 to E9.5]

Project description:Gastruloids are small aggregates of murine Embryonic Stem (ES) cells stimulated to undergo gastrulation-like symmetry breaking events in vitro (van den Brink, S. C. et al. 2014, Simunovic, M. & Brivanlou, A. H 2017). We analyzed the transcriptomic profiles of gastruloids at different time-points after aggregation (AA) and compared them with those of mouse embryo at different stages, raging from e6 to e9.5. We show that gastruloids are capable of organizing a post-occipital pattern of neural, mesodermal and endodermal derivatives that mimics that of the embryo in terms of gene expression.

Single-cell and spatial transcriptomics reveal somitogenesis in gastruloids

Project description:Gastruloids are three-dimensional aggregates of embryonic stem cells (ESCs) that display key features of mammalian post-implantation development, including germ layer specification and axial organization. Gastruloids have mostly been characterized with microscopy-based approaches, limiting the number of genes that can be explored. It is therefore unclear to what extent gene expression in gastruloids reflects in vivo embryonic expression. Using both single-cell RNA-seq (scRNA-seq) and spatial transcriptomics we systematically compared cell types and spatial expression patterns between mouse gastruloids and mouse embryos.

Mannose is crucial for mesoderm specification and symmetry breaking in gastruloids

Project description:Patterning and growth are fundamental features of embryonic development that must be tightly coordinated during morphogenesis. As metabolism can control cell growth while also providing mechanistic links to developmental signalling pathways, it is ideally placed to enable this coordination. To understand how metabolism impacts early mesoderm specification, we used mouse embryonic stem (ES) cell-derived gastruloids, as these enable temporal control over metabolic manipulations and can be generated in large quantities. Gastruloids show mosaic expression of two glucose transporters,Slc2a1andSlc2a3both of which co-express with the expression of both the mesodermal markerT/Braand the neural markerSox2. To understand the significance of cellular glucose uptake in development, we used the glucose metabolism inhibitor 2-deoxy-D-glucose (2-DG). 2-DG specifically blocks the expression ofT/Brawithout affecting the expression ofSox2and abolishes axial elongation in gastruloids. Surprisingly, removing glucose completely from the medium did not phenocopy 2-DG treatment despite a significant decline in glycolytic intermediates occurring under both conditions. As 2-DG can also act as a competitive inhibitor of mannose, we added mannose together with 2-DG and found that it could rescue the mesoderm specification. Together, our results show that while mannose is crucial for mesoderm specification, the glycolytic pathway is dispensable at early stages ofT/Braexpression in gastruloids.

Single Cell RNA-seq time course of mouse gastruloids at 0h (mESCs), 24h, 48h and 72h post-aggregation

Project description:Single cell transcriptomic study (using 10x Genomics v3 kits) of gastruloids, aggregates of mESCs, at different developmental timepoints (24h, 48h and 72h post-aggregation). mESCs, corresponding to the 0h timepoint, were also sequenced. The aim of this study was to delineate the cell state transition dynamics underlying anteroposterior symmetry breaking and germ layer formation in gastruloids. Gastruloids used in this study were generated from Bra::GFP reporter mESCs (Fehling et al., 2003).
