Project description:Inflammatory bowel diseases (IBDs) including ulcerative colitis (UC) and Crohn’s disease (CD) are chronic inflammatory diseases with increasing worldwide prevalence that show a perplexing heterogeneity in manifestations and response to treatment. We applied spatial transcriptomics at single-cell resolution (CosMx Spatial Molecular Imaging) to human inflamed and uninflamed intestine.
Project description:Peripheral blood-derived macrophages were stimulated with viral-like particles isolated from colonic resections from patients with Crohn's disease (CD), ulcerative colitis (UC), or non-IBD controls diagnoses. RNAseq was performed to unbiasedly assess the transcriptional responses to these stimuli and revealed highly divergent macrophage transcriptional programs in response to non-IBD compared to IBD VLP.
Project description:Gene expression in the colonic mucosa of wild-type and p38a-knockout intestinal epithelial cells (IECs) were compared. C57BL/6 wild-type mice, and intestinal epithelial cell-specific p38a-knockout mice on a C57BL/6 background were used for isolation of colonic mucosa
Project description:Gene expression in the colonic mucosa of wild-type and p38a-knockout intestinal epithelial cells (IECs) were compared. C57BL/6 wild-type mice, and intestinal epithelial cell-specific p38a-knockout mice on a C57BL/6 background were used for isolation of colonic mucosa Gene expression in each genotype was analyzed in triplicate.
Project description:Inflammatory bowel diseases (IBDs) including ulcerative colitis (UC) and Crohn’s disease (CD) are chronic inflammatory diseases with increasing worldwide prevalence that show a perplexing heterogeneity in manifestations and response to treatment. We applied single cell RNA sequencing (scRNAseq) a to colonic tissue from a combined healthy, UC and CD cohort.
Project description:CosMx SMI is a high-plex in situ analysis platform to provide spatial multiomics with formalin-fixed paraffin-embedded (FFPE) and fresh frozen (FF) tissue samples at cellular and subcellular resolution. CosMx SMI is an integrated system with mature cyclic fluorescent in situ hybridization (FISH) chemistry, high-resolution imaging readout, interactive data analysis and visualization software. Herein we used the CosMx SMI with the CosMxTM Human Universal Cell Characterization RNA Panel (1000-plex) supplemented with 14 custom genes of interest to probe different disease stages of MASLD/MASH, previously known as NAFLD.
