Project description:5000 target cells per sample where sequenced from 2 gastric tumor samples and 1 sample of adjacent gastric mucosa Twist2Cre;Lkb1fl/+;RosaRTdtomato+/- mice. Drop-seq 10X Genomics (10X v3 library kit) was used for single cell barcoding and library preparation. Samples were sequenced with Novaseq6000.
Project description:Human induced pluripotent stem cell-derived kidney organoids have potential for disease modelling and regenerative medicine purposes. However, they lack a functional vasculature and remain immature in in vitro culture. Here, we transplanted kidney organoids at day 7+12 of differentiation in the coelomic cavity of chicken embryos and then compared them to their respective untransplanted controls at d7+13 and d7+20 using scRNAseq and imaging modalities. We demonstrate vascularization and enhanced maturation of transplanted kidney organoids.
Project description:To investigate the impact of hormonal modulation on neurodevelopmental processes, we performed single-cell RNA sequencing (ScRNA-seq) on neural organoids derived from two genetically validated human induced pluripotent stem cell (hiPSC) control lines (CTL08, male; CTL04, female). Organoids were chronically exposed to agonists and inhibitors targeting seven hormone signaling pathways known to regulate human brain development: androgen (AND), estrogen (EST), glucocorticoid (GC), thyroid (THY), retinoic acid (RA), liver X (LX), and aryl hydrocarbon (AH). Appropriate negative controls were included, consisting of vehicle-treated (DMSO) and/or untreated samples depending on the experimental condition.

Project description:To delineate the potential molecular mechanisms underlying the communication between neutrophils and NK cells, we performed scRNAseq of the neutropenic bone marrow (12 months after transplantation of Cebpacre/+ Sbds +/+ or F/F cells). To this end, bone marrow cells were subsorted into HSC+MPP (LKS CD48-), HPC1 (LKS CD48+CD150-), B and T cells (B220+, CD3+), NK cells (NK1.1+ NKp46+) and a myeloid ‘rest’ fraction (B220-,CD3-,NKp46- and NK1.1-) and sorted fractions pooled together to obtain robust representation of all bone marrow cell types in the scRNAseq data
Project description:To analyse lesion-induced gene regulation in macrophage and microglia at single cell resolution, we performed single cell RNAseq on FACS-isolated mpeg1.1:GFP cells from the spinal cord at 24 hours post-lesion (hpl) after spinal injury at 3 days post-fertilisation (dpf), compared to age-matched uninjured animals.
Project description:To analyse lesion-induced gene regulation in progenitor cells at single cell resolution, we performed single cell RNAseq on FACS-isolated her4.3:GFP progenitor cells from the spinal cord at 24 hours post-lesion (hpl) after spinal injury at 3 days post-fertilisation (dpf), compared to age-matched uninjured animals.
Project description:Adult zebrafish hearts have the ability to regenerate. The roles of non-myocytes in this process have remained elusive. Here, we have performed 2 scRNAseq experiments on interstitial cells. Experiment 1 (E1) included interstitial cells obtained from uninjured, regenerating (3 days, 7 days and 14 days post-apical amputation). Experiment 2 (E2) included cells from uninjured, sham-operated (abdomen opened) and regenerating (3 days post-amputation) with and without MMP inhibitor (NSC40520) treatment. Cells were obtained by heart dissection followed by enzymatic dissociation and FACS sorting of single, viable nucleated cells.
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:We used trophoblast organoids differentiating to extravillous trophoblast (EVT) to study the effects of key cytokines secreted by uterine Natural Killer (uNK) cells on EVT behaviour. Specifically, we exposed the organoids to four uNK-derived cytokines (CSF1, CSF2, XCL1, CCL5) and collected cells at different time points along the EVT differentiation pathway for scRNA-seq. We observe enhanced EVT differentiation in cytokine-treated organoids demonstrated by the increased proportion of late EVT subtypes and regulation of related pathways such as epithelial-mesenchymal transition. Moreover, uNK cytokines affect other processes important during early pregnancy including dampening of inflammatory and adaptive immune responses, regulation of blood flow, and placental access to nutrients.
