Mouse hearts after myocardial infarct

Data set contains samples from isolated cells of murine hearts after myocardial infarction (LAD surgery). We used an endothelial tracing system to mark endothelial cells with EGFP prior to infarct. In brief, Cdh5-ERT2+/-;mT/mG mice, which were used at an age of 10-12 weeks. Cre expression was induced by daily intraperitoneal injections of 2 mg tamoxifen for 1 week in all mice. One week after tamoxifen injection, left anterior descending coronary artery ligation surgery was performed, inducing myocardial infarction. We collected samples at homeostasis, days(d) 1, 3, 7, 14 and 28 after infarction and isolated the non-cardiomyocyte fraction for single cell sequencing. Murine scRNA-seq libraries were prepared using Chromium Single Cell 3′ v3 Reagent Kit (10X Genomics), according to manufacturer’s protocols. Raw reads were mapped against a customized version of mm10 (GRCm38.p4) containing sequences of EGFP and tdTomato.
