Project description:We profiled a time-course single-cell RNA-seq on C57BL/6 mouse ovary from E11.5 to E14.5 to study the cell population heterogeneity and regulation of meiosis initiation. We collected single cell from XX gonads at E11.5, E12.5, E13.5 and E14.5, and were further captured with 10x Genomics based single-cell system. By using single-cell RNA seq, we recapitulated the progression of meiosis using pseudotime ordering of all germ cells and delineated key molecular network among all germ cell clusters. Besides, we provide candidate meiosis stage-specific master regulons along the progression of meiosis and provide detailed transcriptome profile information for controversial Xist+ PGCs. Our data here offers the opportunity for exploring mechanisms underlying germ cell meiosis progression at single cell resolution.

Project description:We generated gene expression profiles of 5 time points in murine lung development (E11.5, E13.5, E14.5, E16.5 and P5). The goal of this study was to establish a reference data set for exploration of large-scale similarities between transcriptomes in development and cancer. Experiment Overall Design: Whole lung expression profiles from C57BL/6J mice at E11.5 (pooled sample), E13.5, E14.5, E16.5 and P5.

Project description:Background: To better understand the role DNA methylation plays in regulating gene expression in the developng heart and furthermore the role it plays in heart development we performed genome wide DNA methylation profiling of embryonic hearts at embryonic day (E)11.5 and E14.5 using methyl sensitive tiny fragment enrichment coupled with massive parallel sequencing by using the methyl-sensitive restriction enzyme HpyCH4IV, recognition site 'ACGT'. Results: We found that global methylation remains stable at analyzed 'ACGT' sites (1.64 million site) in developing hearts between E11.5 and E14.5. However, differential methylation was identified at individual loci enriched at genes involved in heart development suggesting a role for DNA methylation in the developing heart. Used Methyl Sensitive Tiny Fragment Enrichment/Massive Parallel Sequencing (MSFE/MPS) to assay methylation at 'ACGT' sites throughout the genome and generate a developmental profile of DNA methylation in the embryonic heart and to identify differences between developing mouse hearts at E11.5 and E14.5.

Project description:Purpose: We performed a time-course single-cell RNA-seq of the somatic cells of the XX mouse gonads to study the cell population heterogeneity and the genetic program during their differentiation. Methods: We collected gonads from NR5A1-eGFP transgenic embryos at six embryonic stages: E10.5, E11.5, E12.5, E13.5, E16.5 and P6. Methods: Cells were capture with the C1 autoprep system and cDNA sequenced with Illumina HiSeq 2000. Results: One cell population was detected at E10.5 and give rise to both Granulosa and steroidogenic precursor cells. A precursor cell population remains undifferentiated at P6 and are likely to be theca cell precursors. Conclusion: Our study is, to date, the most granular transcriptomic study of the developing mouse ovary and provide a more complete model of somatic cell differentiation during female sex determination.

Project description:During development of the mammalian central nervous system (CNS), neurons and glial cells (astrocytes and oligodendrocytes) are generated from common neural precursor cells (NPCs). However, neurogenesis precedes gliogenesis, which normally commences at later stages of fetal telencephalic development. Astrocyte differentiation of mouse NPCs at embryonic day (E) 14.5 (relatively late gestation) is induced by activation of the transcription factor STAT3, whereas at E11.5 (mid-gestation) NPCs do not differentiate into astrocytes even when stimulated by STAT3-activating cytokines such as leukemia inhibitory factor (LIF). This can be explained in part by the fact that astrocyte-specific gene promoters are highly methylated in NPCs at E11.5, but other mechanisms are also likely to play a role. We therefore sought to identify genes involved in the inhibition of astrocyte differentiation of NPCs at midgestation. We first examined gene expression profiles in E11.5 and E14.5 NPCs, using Affymetrix GeneChip analysis, applying the Percellome method to normalize gene expression level. We then conducted in situ hybridization analysis for selected genes found to be highly expressed in NPCs at midgestation. Among these genes, we found that N-myc and high mobility group AT-hook 2 (Hmga2) were highly expressed in the E11.5 but not the E14.5 ventricular zone of mouse brain, where NPCs reside. Transduction of N-myc and Hmga2 by retroviruses into E14.5 NPCs, which normally differentiate into astrocytes in response to LIF, resulted in suppression of astrocyte differentiation. However, sustained expression of N-myc and Hmga2 in E11.5 NPCs failed to maintain the hypermethylated status of an astrocyte-specific gene promoter. Taken together, our data suggest that astrocyte differentiation of NPCs is regulated not only by DNA methylation but also by genes whose expression is controlled spatio-temporally during brain development. Experiment Overall Design: Neuroepithelial cells(NPCs) were prepared from telencephalons of E11.5 and E14.5 mice and cultured in N2-supplemented Dulbecco's Modified Eagle's Medium with F12 (GIBCO) containing 10 ng/ml basic FGF (R&D Systems) (N2/DMEM/F12/bFGF) on culture dishes (Nunc) or chamber slide (Nunc) which had been precoated with poly-L-ornithine (Sigma) and fibronectin (Sigma). E11.5 NPCs were cultured for one day and E14.5 NPCs were for four days.

Project description:Transcriptional profiling of individual mouse embryonic (e11.5) XY gonads comparing inbred strains that are sensitive (C57BL/6J) and resistant (129S1/SvImJ) to XY sex reversal, and their reciprocal F1 hybrids. Experiment Overall Design: Two-color Agilent microarray profiles of 20 individual pairs of e11.5 XY gonads, including 5- C57BL/6J, 5- 129S1/SvImJ, 5- (B6x129S1)F1, and 5- (129S1xB6)F1 samples. Within each strain, samples were collected from multiple litters to account for potential litter biases. All samples were processed following the same protocol.
