Single-cell RNA sequencing data from murine hearts after infarction with Collagen-2 tracing

Data set contains samples from isolated cells of murine hearts after myocardial infarction (LAD surgery). We used Col1a2 tracing system to mark Collagen expressing cells within d3 to d7 post infarct. In brief, adult Col1a2-ERT2+/-;mT/mG mice, at an age of 12 weeks (n=4) as well as aged animals with 88-91 weeks (n=4) were used. Left anterior descending coronary artery ligation surgery was performed, inducing myocardial infarction. Homeostasis animals were not operated. For Cre induction we injected 2mg Tamoxifen from d3 to d7 post surgery. All animals were sacrificed 28d post injury. 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.
