Background:

High-content screening generates complex cell phenotype data.
Analyzing drug effects on cellular morphology requires robust computational methods.
Unsupervised approaches offer potential for unbiased biological insights.

Purpose of the Study:

To develop an unsupervised, scalable, and interpretable cell profiling framework.
To model differential drug effects on macrophage cell phenotypes.
To identify key cell features for understanding drug mechanisms.

Main Methods:

Utilized maximum relevancy and minimum redundancy criteria for feature selection.
Implemented a 2-stage clustering approach to annotate and merge cells into super-clusters.
Generated interpretable cell profiles based on super-cluster proportions under various drug treatments.

Main Results:

Successfully modeled differential drug effects on IC-21 macrophages treated with cytoskeletal drugs.
Validated the framework using chi-squared statistics and 5-fold cross-validation.
Demonstrated statistically similar profiles for drugs with equivalent mechanisms of action.
Identified distinct trends for 5 cytoskeletal drugs under varied conditions.

Conclusions:

The developed framework provides an interpretable method for analyzing high-content screening data.
Super-cluster profile changes effectively reveal drug-induced biological effects.
The approach facilitates the understanding of drug mechanisms and comparative analysis.
