A single-cell transcriptomics approach reveals high-resolution cellular signatures in Crohn's disease
Journal of Crohn's and Colitis(2020)
摘要
Background Single-cell RNA sequencing (sc-RNAseq) provides high-resolution analysis of individual cells and cell clusters within complex tissues like the intestinal mucosa. No study to date has applied this novel technology to understand the complexity of intestinal inflammation in Crohn’s disease (CD) patients. Our aim is to identify the cellular subsets present in healthy and inflamed colon, and to describe how individual subsets are regulated in active CD. Methods Colon biopsies from a healthy control (HC) and two patients with endoscopically active colonic CD were collected and processed by enzymatic digestion and cell sorting to discard dead cells. Single-cell suspensions were processed by droplet-based protocol 10× chromium system followed by library preparation and sequencing. Sequencing data were aligned and quantified using Cell Ranger. Downstream …
