Project description:RNA sequencing was performed on 5454 single cells from dentate gyrus of CD-1 mice, sampled at postnatal day 12, 16, 24 and 35, with the aim of studying the postnatal dentate gyrus neurogenesis.
Project description:RNA sequencing was performed on 24185 single cells from dentate gyrus of CD-1, C57Bl/6, or hGFAP-GFP reporter mice, sampled at ages ranging from embryonal day 16.5 to postnatal day 132, with the aim of comparing peri- and postnatal neurogenesis in the dentate gyrus
Project description:The gene expression patterns in the dentate gyrus of wild-type mice during postnatal development were examined using Affymetrix GeneChip arrays.
Project description:Spatially-resolved transcriptomics methodologies are revolutionizing our understanding of complex tissues, but their elevated costs represent still a bottle-neck for their democratization. In this work we present a low-cost strategy for manufacturing molecularly double-barcoded DNA arrays, enabling large-scale spatially-resolved transcriptomics studies. We applied this technique to spatially resolve gene expression in several human brain organoids, including the reconstruction of a 3-dimensional view from multiple consecutive sections, revealing gene expression divergencies throughout the tissue.

Project description:Spatially resolved transcriptomics in plants
Project description:To investigate the effect of repeated neural overactivation in the chromatin accessibility of dentate gyrus neurons, we optogenetically stimulated mouse dentate gyrus repeatedly.
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 with 10x Visium Spatial transcriptomics of the entire maternal-fetal interface including the myometrium, allowing us to resolve the full trajectory of trophoblast differentiation.
Project description:Single-cell RNA sequencing was performed on dentate gyrus of C57Bl/6 mice at ages ranging from 3 MO to 21 MO. Spatial transcriptomics was performed on whole brain sections from cage littermates
Project description:We used spatially resolved transcriptomics to define the cellular diversity within a sonic hedgehog (SHH) patient-derived model of Medulloblastoma (MB) and identify how cells specific to a transcriptional state or spatial location are pivotal in responses to treatment with the CDK4/6 inhibitor, Palbociclib. Our analysis reveals that SHH tumour in the mouse brain contains multiple malignant transcriptional states, recapitulating the extent of intratumoural cellular diversity identified in primary human SHH MB. Our study offers new insight into the previously described features of CDK4/6 inhibition in MB, with Palbociclib treatment inducing neuronal differentiation across all remaining cell types comprising the bulk of the SHH patient-derived orthotropic xenograft model. This study is, to the best of our knowledge, the first spatially resolved gene expression atlas of SHH PDOX MB and acts as proof-of-principle for the use of ST-seq in identifying spatially-organised tumour heterogeneity of MB.
Project description:Bcl11b plays an important role in postnatal dentate gyrus development and adult neurogenesis. To determine its role in adult neurogenesis independant from postnatal development the Bcl11b mutation was induced at the age of 2 months. Microarray analysis was performed on RNA isolated 4 weeks after the induction of the Bcl11b mutation to determine Bcl11b target genes.
