Computational analysis demonstrates accurate lineage tracking across ten single-cell datasets, highlighting improved trajectory inference in complex biological differentiation.

Key Points

Develop a statistical framework for RNA velocity that overcomes model violations and enforces temporal regularization to accurately reconstruct cell trajectories.
Designed UniTVelo to dynamically model spliced and unspliced RNA kinetics using flexible transcription activities.
Incorporated the estimation of a transcriptome-wide unified latent time.
Evaluated performance across ten single-cell datasets covering diverse biological systems, including hematopoietic differentiation and complex branching lineages.
Successfully recovered expected biological differentiation trajectories across all ten benchmarked datasets.
Accurately reconstructed lineage dynamics in systems characterized by weak transcriptional kinetics and intricate multi-branch architectures where standard methods failed.
