Project description:With the increasing use of Assisted Reproductive Technologies (ART) for treatment of human infertility, there is an increasing requirement for embryo culture conditions that perform as similar to nature as possible. How good the match, however, cannot be tested experimentally in human. We solved the central question of how well ART culture protocols prepare embryos for postimplantation development, under the provisions of the 'mouse embryo assay' (MEA). Our side-by-side comparison of 8 conditions [i.e., 3 culture conditions (KSOM, HTF and ISDM1) plus the in vivo system in two different mouse strains (B6 and CD1)] shows that mouse embryos cultured under ART conditions are differentially primed for postimplantation development, and that certain ART protocols outperform the oviduct. The distinct performances of blastocysts formed in ART vs. oviduct do not correlate with any significant transcriptome changes, whereas protein analysis by immunoconfocal microscopy reveals differences in the allocation of embryonic cells to the three germ layers of blastocysts. We conclude that in vitro technology is not always a defective copy of nature, and that the choice of ART protocol primes the embryos for subsequent development. 22 samples were analyzed.

Project description:We did bulk and single cell RNA sequencing of blastocysts, blastoids, trophoblast stem cells (TSC) and embryonic stem cells (ESC). The goal of these experiment is to describe the transformations of the transcriptome occurring within cells (TSC, ESC) upon formation of a blastoid. E3.25 and E3.5 blastocysts are used as controls. To this end, we first did RNA sequencing of intact structures (E3.25 and E3.5 blastocysts, blastoids, and parental cell lines). In a different series of experiments, we micro-dissected blastocyst, blastoid or trophosphere structures into single cells, and sequenced their mRNAs, to infer cell identity and transcriptome variations.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:Single-nucleus RNA sequencing (snRNA-seq) was used to profile the transcriptome of 5,264 nuclei in mouse adult testis. This dataset includes two samples from two different individuals. This dataset is part of a larger evolutionary study of adult testis at the single-nucleus level (97,521 single-nuclei in total) across mammals including 10 representatives of the three main mammalian lineages: human, chimpanzee, bonobo, gorilla, gibbon, rhesus macaque, marmoset, mouse (placental mammals); grey short-tailed opossum (marsupials); and platypus (egg-laying monotremes). Corresponding data were generated for a bird (red junglefowl, the progenitor of domestic chicken), to be used as an evolutionary outgroup.

Project description:We quantified the targets and kinetics of DNA methylation acquisition in mouse embryos, and determined the contribution of the de novo methyltransferases DNMT3A and DNMT3B to this process. We provide single-base maps of cytosine methylation by RRBS from the blastocysts to post-implantation stages and in embryos lacking DNMT3A or DNMT3B activity, and performed RNA-Seq in embryos lacking DNMT3B activity. We sequenced RRBS libraries prepared from genomic DNA isolated from embryos at consecutive stages of development between E3.5 and E11.5,and adult differentiated cells (sperm, liver). We performed RRBS on blastocysts at E3.5/E4.5, dissected epiblasts at E5.5/E6.5/E7/5, whole embryos at E8.5/E10.5 and limbs at E11.5. RRBS experiments in Dnmt3a-/- and Dnmt3b-/- embryos were performed in biological duplicates on individual embryos. We sequenced RNA-Seq libraries prepared from total RNAs of three WT and Dnmt3b-/- littermate embryos collected at E8.5.
