This study uses single-cell RNA-sequencing and spatial transcriptomics to analyze the spatio-temporal dynamics of the fibrotic niche in cardiac repair after ventricular injury in adult mice, identifying key cell interactions and regulatory mechanisms.

This study examines age-related changes in cardiac Schwann cells, parasympathetic nerve fibers, and M2R expression in mice, finding reduced SC density, fewer parasympathetic fibers, and lower M2R expression in aged hearts, which correlates with increased arrhythmia risk.
