scRNA-seq of mouse 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) induced liver injury model
Regulatory T cells (Tregs) were shown to protect from cholestatic liver injury. Here we investigate whether amphiregulin (AREG), a ligand for epithelial growth factor receptor (EGFR) which promotes epithelial repair, mediates innate Treg functions in cholangiopathies. Mice were fed with diet containing 0.1 % of the xenobiotic 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) for 14 days to induce sclerosing cholangitis, followed by a 28-day recovery period (without DDC). Liver mononuclear and epithelial cells were enriched and subjected to single-cell sequencing at six time points: baseline, at days 7 or 14 of DDC treatment, and following a 7-, 14- or 28-day recovery period from 14 days of DDC treatment. Overall design: For our time course, 8-week wild type C57Bl/6 mice were fed with 5058 chow admixed with 0.1% DDC for 14 days and then allowed to recover for an additional 7-28 days (5058 chow without DDC). Liver mononuclear and epithelial cells were enriched and subjected to single-cell sequencing at six time points: baseline, at days 7 or 14 of DDC treatment, and following a 7-, 14- or 28-day recovery period from 14 days of DDC treatment.
