This study introduces virtual-cell software for analyzing eukaryotic cell chemotaxis. The tool simulates cell movement along chemical gradients, aiding research in development and disease.

Area of Science:

Cell Biology
Biophysics
Computational Biology

Background:

Eukaryotic cell navigation along spatial gradients is vital for development, regeneration, and cancer.
Chemotaxis, a key process, is modeled by phosphoinositide-based phase separation at the plasma membrane.
This process, triggered by chemoattractants, drives directional cell motility.

Purpose of the Study:

To provide a computational tool for studying eukaryotic cell chemotaxis.
To enable detailed spatiotemporal analysis of in silico chemotaxis experiments.
To offer user control over experimental parameters and chemoattractant source configurations.

Main Methods:

Development of virtual-cell software for simulating chemotaxis.
Implementation of spatiotemporal analysis capabilities within the software.
