Amrute, Lai et al. performed single-nucleus RNA sequencing and compared the cellular and transcriptomic features of hearts from non-diseased donors, from patients with heart failure who recovered systolic function after left ventricular assist device implantation and from patients who did not recover. The analyses identified cell-type-specific signatures of recovery and revealed the downregulation of RUNX1 expression in macrophages and fibroblasts as a predictor of recovery, as confirmed by in silico simulations and re-analysis of data from a mouse model of cardiac functional recovery.
