Area of Science:

Cell Biology
Biostatistics
Microscopy

Background:

Cellular function is often studied by analyzing cell morphology after experimental manipulation.
3D fluorescent microscopy with protein markers is crucial for functional analysis, but quantitative comparison tools are limited.
Existing methods lack user-friendliness for biologists without extensive statistical expertise.

Purpose of the Study:

To develop a novel statistical method for quantitative comparison of cellular morphologies from fluorescent images.
To provide an automated, unbiased tool for cell biologists to analyze multifactorial image data.
To bypass computationally intensive resampling techniques for P-value calculation.

Main Methods:

Intracellular structures are transformed into kernels.
A multivariate, nonparametric, asymptotically normal two-sample test is developed.
Parameters are estimated directly from data, enabling a black-box approach.

Main Results:

The new statistical test quantitatively compares cellular morphologies.
Asymptotic normality simplifies P-value computation compared to resampling methods.
The method was validated on synthetic and experimental data, including multivesicular body morphology changes after microtubule disruption.

Conclusions:

The developed density-based comparison method offers automated and unbiased cell morphology analysis.
This technique significantly detects changes in intracellular structures like multivesicular bodies.
The underlying mathematical framework is generalizable for comparing any two data samples.
