To address the challenges of cell asynchrony and multiple time points in scRNA-seq analysis.
To accurately identify differentially expressed genes and cell subclusters that change over time.

Main Methods:

Proposed scTITANS, a novel method for time-series scRNA-seq data analysis.
Utilized pseudotime from trajectory inference to correct for cell asynchrony.
Incorporated a time-dependent covariate based on time-series analysis.

Main Results:

scTITANS accurately identifies differentially expressed genes and cell subclusters in time-series scRNA-seq data.
Demonstrated superior accuracy and quantitative performance compared to existing methods.
Effectively handles cellular heterogeneity and leverages temporal information.

Conclusions:

scTITANS provides a robust and accurate solution for analyzing time-series scRNA-seq data.
The method overcomes limitations of current approaches by correcting cell asynchrony.
scTITANS is expected to drive new breakthroughs in various research areas utilizing time-series single-cell sequencing.
