The time-resolved scRNA-seq (tscRNA-seq) provides the possibility to infer physically meaningful kinetic
parameters, e.g., the transcription, splicing or RNA degradation rate constants with correct magnitudes, and
RNA velocities by incorporating temporal information. Previous approaches utilizing the deterministic dynamics
and steady-state assumption on gene expression states are insufficient to achieve favorable results for the
data involving transient process. We present a dynamical approach, Storm (Stochastic models of RNA metabolic-labeling),
to overcome these limitations by solving stochastic differential equations of gene expression dynamics. The derivation
reveals that the new mRNA sequencing data obeys different types of cell-specific Poisson distributions when jointly
considering both biological and cell-specific technical noise. Storm deals with measured counts data directly and
extends the RNA velocity methodology based on metabolic labeling scRNA-seq data to transient stochastic systems.
Furthermore, we relax the constant parameter assumption over genes/cells to obtain gene-cell-specific
transcription/splicing rates and gene-specific degradation rates, thus revealing time-dependent and cell-state
specific transcriptional regulations. Storm will facilitate the study of the statistical properties of tscRNA-seq data,
eventually advancing our understanding of the dynamic transcription regulation during development and disease.
