The paper investigates the reliability of mitochondrial DNA variants as lineage markers, finding that most are pre-existing heteroplasmy rather than de novo mutations, and introduces a score to identify reliable markers.

scPhyloX infers tissue development and tumor evolution dynamics using single-cell phylogenetic trees, revealing novel insights into stem cell overshoot, hematopoietic progenitor clonal expansion, and colorectal tumor subclonal selection.

The paper introduces PhyloVelo, a method that uses monotonically expressed genes to reconstruct cell fate transitions, outperforming existing approaches in embryo development and tumor evolution analysis.
