Computational analysis reveals that transcriptional diversity determines cellular differentiation state across diverse tissues, highlighting a robust platform for mapping developmental trajectories.

Key Points

To establish whether transcriptional diversity serves as a universal determinant of developmental potential and to build a predictive computational framework for inferring differentiation states from single-cell RNA sequencing data.
Quantified the number of expressed genes per cell as a metric of transcriptional diversity in single-cell RNA sequencing (scRNA-seq) datasets.
Developed CytoTRACE, a computational framework designed to reconstruct cellular hierarchies and predict differentiation trajectories without prior lineage knowledge.
Evaluated performance across 52 experimentally validated developmental trajectories in multiple tissue types and model organisms, benchmarking against prior computational tools and approximately 19,000 annotated gene sets.
CytoTRACE outperformed existing trajectory inference algorithms and nearly 19,000 annotated gene sets across 52 benchmark differentiation trajectories.
The framework accurately identified quiescent stem cells and pinpointed specific genes implicated in breast cancer development.
