Project description:Study of the emergence of the rare 2C like cell population upon Retinoic Acid treatment. Transcriptionally characterise the different cell populations emerging at different timepoints upon Retinoic Acid treatment and identify genes driving cell fate decisions.
Project description:CIARA (Cluster Independent Algorithm for the identification of RAre cell types) is tested on mouse embryonic stem cell treated for 24h with Retinoic Acid.
Project description:We set up a 3D model based on iPSCs derived from patients with familial forms of Alzheimer’s disease (AD) and healthy non-demented control. We created cerebral organoids (COs), verified their ability to mimic AD in vitro, and used it to explore early events and the progression of AD pathogenesis. Our data reveal that despite similar expression of cell-type-specific genes during CO maturation in vitro, AD-iPSCs derived COs show limited tissue patterning and altered cellular development. These findings complement unique single-cell sequencing data of AD-iPSCs derived COs confirming this observation and uncovering that a sub-set of neurons in AD-iPSCs likely differentiates prematurely while at the same time retaining the expression of progenitor marker PAX6.
Project description:Aim of this experiment was to characterize whether SPP1 released from the hippocampal perivascular space could imprint microglia transcriptional states. We performed scRNA-seq analysis on sorted CD140a+ perivascular fibroblast (PVF), CD45highCD11intCD206+ perivascular macrophage (PVM) and CD45intCD11intCX3CR1high microglial cell from dissected hippocampi of 6-month old wild type vs SPP1KO/KO vs AppNL-F mice vs AppNL-FxSpp1KO/KO mice. Cells were isolated from dissected hippocampi as previously described (Sala Frigerio et al.,2019).
Project description:In this project we explore the cellular heterogeneity of a mouse model of heart failure with preserved ejection fraction (HFpEF) involving a two-hit model of feeding a high fat diet (HFD) along with L-NAME administration. Healthy adult male mice (C57BL/6J inbred) were fed either a normal chow diet or HFD/L-NAME for 10 weeks or 15 weeks before performing sequencing experiments. Both cardiomyocytes (CMs) and total interstitial population (TIP) were captured using a protocol to jointly capture and sequence single-nuclei (for cardiomyocytes) and single-cells (for TIP) using the 10x Genomics Chromium system.
Project description:Single-cell RNA-seq of mouse WT retinas and two Nr2e3 mutant retinas, ∆27 and ∆E8 (containing a 27 nucleotide in-frame deletion or a complete exon 8 deletion, respectively). The ∆27 retinas were used as a model for enhanced S-cone syndrome phenotype in humans, while the ∆E8 retinas show a progressive retinal degeneration similar to human retinitis pigmentosa patients. This data was used to explore the role of Nr2e3 in cone and rod photoreceptor differentiation.
Project description:To test whether dendritic cells from patient-derived tumor digests can be activated by agonists and which genes are regulated, we performed a single-cell RNA-seq of immune cells (CD45+) from 4 donors.
Project description:To further explore the transcriptional changes in the kidney transplant biopsy at time of rejection, scRNAseq analysis was performed on 16 kidney transplant biopsy-derived cells using 10X Genomic technology.
Project description:Single cell RNAseq of Neural-derived haploid and diplod human embryonic stem cells, validating successful differentiation of haploid hESCs into neurons
Project description:The unbiased approach to determine transcriptional profiles of sorted NKp46+ cells from the small intestine of WT and HIF-1α KO mice.
