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:Female cystic fibrosis (CF) patients are confronted with fertility deficiency, experiencing difficulties in getting pregnant. Previous findings using CF mouse models indicate that CF negatively impacts female fertility in mice as it does in humans. Underlying reasons remain elusive. In particular, it has only poorly been studied whether the endometrium, the inner lining of the womb and crucial tissue for embryo implantation, plays a role. Here, we applied single cell transcriptomics of wild-type (F508del <wt/wt>; WT) and CF (F508<del/del>) mouse uteri from the Cftr<tm1eur> mouse model, to get a detailed view on cellular and molecular/pathway differences in CF versus WT endometrium. Five uteri (WT: 3, CF: 2) were assessed in the estrus cycle of the estrous cycle, one CF uteri was sequenced during the diestrus cycle phase.
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.
