Single-cell RNA sequencing of meniscus from ACTA2-lineage traced mice, rats and dogs

ABSTRACT: This study presents a cross-species single-cell transcriptomic atlas of the meniscus. The analysis includes genetic lineage tracing mice, wild-type rats, and dogs. Genetic Lineage Tracing Mice: ACTA2-CreERT mice (generated via CRISPR/Cas9 knock-in at the Acta2 locus) were crossed with R26-CAG-LSL-tdTomato reporter mice. All mice received tamoxifen (75 mg/kg, i.p. for 5 days) to induce tdTomato expression in ACTA2-lineage cells. Menisci were harvested from an early post-induction cohort at 2 weeks (n=13) and a late cohort at 10 weeks of age (n=10). Other Species: Menisci were also analyzed from 12-week-old male Sprague-Dawley rats (n=4) and 12-month-old male beagles (n=2). Single-cell suspensions were captured and barcoded using the BD Rhapsody system. Libraries were constructed with the BD
