Background:

Single-cell transcriptomics combined with perturbations is key to understanding cellular responses.
Current computational methods often overlook cell-state-specific variations and lack explainability.

Purpose of the Study:

To introduce CellCap, a deep generative model for analyzing single-cell perturbation experiments.
To address the limitations of existing methods by capturing cell-state-specific responses and enhancing model interpretability.

Main Methods:

CellCap utilizes sparse dictionary learning in a latent space to identify transcriptional response programs.
An attention mechanism is employed to map cell states to their specific perturbation responses.

Main Results:

CellCap successfully deconstructs cell-state-specific perturbation responses.
The model demonstrates interpretability in simulated and real single-cell perturbation datasets.
Identified relationships between cell state and perturbation response, offering novel biological insights.

Conclusions:

CellCap provides a powerful, interpretable framework for single-cell perturbation data analysis.
The model advances the understanding of cellular heterogeneity in response to perturbations.
Offers a new computational approach to uncover complex biological mechanisms governing cellular behavior.
