Stromal evolution of cancer-associated fibroblasts in PDAC GEMMs

ABSTRACT: With the advent of cancer immunotherapy, intense investigation has been focused on tumor-infiltrating immune cells. With only a fraction of patients responding to these new therapies, a better understanding of all elements of the tumor microenvironment (TME) that may influence therapeutic outcome is needed. Stromal elements of the TME, chiefly fibroblasts, have emerged as potential contributors to tumor progression and most recently resistance to immunotherapy, but their precise composition and clinical relevance remain incompletely understood. Here we use single-cell transcriptomics to chart the fibroblastic landscape during pancreatic ductal adenocarcinoma (PDAC) progression in animal models, identifying two healthy tissue fibroblast subsets that co-evolve along individual trajectories into four subsets of carcinoma-associated fibroblasts (CAFs).

Single-cell Gene Expression Flex analysis on patient derived xenografts (PDX) of lung cancer cells with minimal host tumor microenvironment (TME) cells

Project description:To goal of the experiment is to assess whether we can profile enough cells corresponding to the host TME. In this PDX model, most of the cells correspond to the xenograft material, with limited amounts of host TME cells. To this aim we loaded 16 times more cells hybridized with the mouse probe set compared to the human hybridization.

scRNA-seq of canalicular stage human fetal lung cultured under air-liquid interface

Project description:Small pieces (<0.5 cm of diameter) were isolated from distal regions of 125 day male human fetal lung and cultured on floating poly-carbonate membranes on top of serum and growth factor free medium under air-liquid interface conditons (ALI). ALI explants underwent changes in gene expression indicative of alveolar epithelial cell differentiation under these conditions. scRNA-sequencing was performed on fetal tissue prior to culture (day 0) and day 3, 6, 9 and 12 of ALI explant culture.

scRNA-seq of Human Alveolar Type 2 Cell Organoids

Project description:Alveolar type 2 (AT2) cells function as stem cells in the adult lung and aid in injury-repair. The current study aimed to understand the signaling events that control differentiation of this therapeutically relevant cell type during human development through differentiation of lung progenitor organoids to AT2 cells and benchmarking against primary AT2 organoids.

RNA-Seq of isolated pancreatic stellate cells from mice with autoimmune pancreatitis and chronic pancreatitis

Project description:Autoimmune pancreatitis (AIP) is a disease with unclear immunologic triggers. This study shows that the pancreatic stellate cells(PSCs) are involved in the regulation of the immune response and can cause autoimmunity when the NF-κB signalling in these cells is disrupted. The PSCs were isolated from animals which show autoimmune pancreatitis (NEMO knockout group) or chronic pancreatitis (NEMO wildtype group).

ScRNA-seq of stromal cells in WT and LRRC15 DTR mice

Project description:KPR tumors were subcutaneously implanted in Lrrc15DTRGFPwt/wt (DTR–) or Lrrc15DTRGFPwt/ki (DTR+) mice and DT treatment was initiated in both DTR– and DTR+ mice when tumors reached a mean volume of 100-200mm3. scRNAseq of CD24-CD45- stromal cells from a total of 40 tumor-bearing animals across both DTR– and DTR+ genotypes was carried out at four different time points including 10 days post tumor implantation and immediately prior to initiation of DT treatment (IOT) (referred to as day 0) and on days 7, 14, and 21 post IOT.

IL-33 provision by reprogrammed tumor fibroblastic stromal cells promotes local T cell activity and facilitates melanoma eradication

Project description:The tumor microenvironment (TME) is a complex mixture of tumor cells, immune cells, endothelial cells and fibroblastic stroma cells (FSC). While cancer-associated fibroblasts are generally seen as a tumor-promoting entity, it is conceivable that distinct FSC populations within the TME contribute to immune-mediated tumor control. Here, we show that intra-tumoral injection of a recombinant LCMV-based vaccine vector (r3LCMV) expressing the melanocyte differentiation antigen TRP2 results in T cell-dependent eradication of melanomas. Analysis of the TME revealed that viral vector transduction precipitates activation of particular FSC subsets. Using single-cell RNA-seq analysis, we identified a Cxcl13-expressing FSC population with a pronounced immune-stimulatory signature and increased expression of the inflammatory cytokine IL-33. Genetic ablation of Il33 in Cxcl13-Cre+ FSC impeded functionality of intratumoral T cells and consequently tumor control. Thus, reprogramming of distinct FSC subsets in the TME through LCMV-based vectors efficiently promotes tumor eradication by locally sustaining the activity of tumor-specific T cells.

Single cell RNA-seq of iPSC-derived Kidney Organoids treated with TGF-Beta 1 and GSK343 compared with vehicle treated control

Project description:This study used scRNA-seq to characterise the transcriptome in 26 day-old iPSC-derived kidney organoids, treated with TGFB1, the EzH2 inhibitor GSK343, a combination of both or a vehicle control for 48 hours (days 24-26) before harvesting. 2 organoids per condition were pooled and dissociated using a cold-active protease. Nuclei were extracted and profiled using the 10X Genomics Single-cell 3' V3 kits. Libraries were sequenced using paired-end reads on an Illumina NextSeq 500. Initial processing was performed using CellRanger v3.1.0 (10X Genomics).

Single cell RNA-seq of hiPSC-derived kidney organoids differentiated within self-assembling peptide hydrogels and the animal-derived matrix Matrigel

Project description:scRNA-seq was used to characterise hiPSC-derived kidney organoids differentiated within fully synthetic self-assembling peptide hydrogels of variable mechanical strengths and compare these to organoids differentiated within the animal-derived matrix, Matrigel. Organoids were matured in the respective matrices until day 24 of differentiation and 6 organoids per support matrix were then pooled and dissociated using the cold-active protease from Bacillus licheniformis. Cells were processed on the 10x Genomics Chromium platform using the Single-Cell 3’ v3.1 protocol. The NextSeq500 (Illumina) was used to sequence the libraries generated and initial processing of the data was carried out using the 10X Genomic Cell Ranger v3.1.0 pipeline.
