Project description:Comprehensive map of first- and second-trimester gonadal development in humans using a combination of single-cell and spatial transcriptomics, chromatin accessibility assays, and imaging.
Project description:spatial transcriptomics by means of 10x Visium of first and second trimester human reproductive tract (including female and male internal and external genitalia)
Project description:These samples are part of a study to provide a spatially resolved single-cell multiomics map of human trophoblast differentiation in early pregnancy. Here we profiled three human implantation sites (between 6 and 9 post-conceptional weeks, PCW) with snucRNAseq; five decidual and three placental samples from 8-13 PCW by scRNA-seq/snRNA-seq.
Project description:To explore the interactions between the range of maternal and fetal placental cell types present, we profiled the transcriptomes of more than 50,000 single cells from matched first trimester samples of maternal blood and decidua, as well as fetal cells from the placenta itself. RNA-seq was done using the standard 10x chromium v2 chemistry.
Project description:We generated genome-wide maps of DNaseI hypersensitivity in mouse erythroid cells by DNase-Seq. Examination of DNaseI hypersensitivity in mouse erythroid cells.
Project description:We used SLIC-CAGE to map transcriptional start sites (TSSs) of P14 WT and P14 Tbpl2-/- mutant mouse oocytes. Comparison of WT and Tbpl2-/- oocytes demonstrates that Tbpl2 guides transcriptional start site selection in the growing oocyte. This TSS selection is different compared to the canonical somatic type of TSS selection and depends on TATA-like elements as core promoter motifs, recognised by Tbpl2.
Project description:The mutation in the C9orf72 gene with a hexanucleotide repeat has been reported multiple times to be the most common genetic cause of FTD and ALS (Frontotemporal Dementia and Amyotrophic Lateral Sclerosis), both of which are devastating neurodegenerative diseases having no cures currently. Our lab previously created fruit fly models expressing 36(C4G2) repeats, these are highly toxic to adult neurons of fruit flies. This is one of the most commonly used fly models of disease. Like many neurodegenerative diseases, FTD and ALS display selective neuronal vulnerability: only some neuronal populations succumb to disease, even though the toxic species are ubiquitously expressed. Our lab proposes to identify which neuronal populations are selectively depleted in response to the expression of the repeats and analyse which pathways are activated in vulnerable and resistant neuronal populations using our fly model of disease. This is done by scRNA sequencing across multiple time points, tracking disease development. The workflow was first having the flies ready and their brains being dissected. The brains were then dissociated by collagenase and dispase, and the cell suspensions were passed through a 10um cell strainer. The single-cell suspensions were checked for viability and the single-cell libraries were prepared with 10X Chromium 3' platform.
