PhysiCell: an open source physics-based cell simulator

Download the latest version (1.0.0)

Introduction

Many multicellular systems problems can only be understood by studying how cells move, grow, divide, interact, and die. Tissue-scale dynamics emerge from systems of many interacting cells as they respond to and influence their microenvironment. The ideal "virtual laboratory" for such multicellular systems simulates both the biochemical microenvironment (the "stage") and many mechanically and biochemically interacting cells (the "players" upon the stage). PhysiCell was developed to work in concert with BioFVM to fill this role as a virtual laboratory.

Project goals

PhysiCell aims to provide a robust, scalable code for simulating large systems of cells in 3-D tissues on standard desktop computers. Among our design goals:

What's New Back to top

September 27, 2016: We submitted PhysiCell to PLoS Computational Biology as a software article. As part of that submission, PhysiCell is now available as open source, under the BSD license.

Method, accuracy, and performance Back to top

PhysiCell extends the agent-based model from Macklin et al. (2012) to 3D, with improved sub-models for cell volume regulation, cell cycling, apoptosis, and necrosis. It uses cross-platform compatible C++ (tested on OSX, Linux, and Windows), and it has been parallelized using OpenMP. More details will be available once the method is fully published.

Computational cost scales linearly with the number of simulated cells, and we have tested all the major software components for numerical accuracy and convergence. Simulations up to 1 million cells are feasible on a modern Intel i7 processor with 16-32 GB of system memory. Larger simulations are feasible on HPC compute nodes.

We'll post some updated examples once PhysiCell ispublished. In the meantime, please enjoy this early simulation test of a 3-D hanging-drop tumor spheroid.

Licensing and disclaimers Back to top

PhysiCell is licensed under the (3-Clause) BSD License. It is GPL v2 and v3 compatible, and suitable for commercial use in many circumstances.

PhysiCell is an academic/scientific code, and it should not be used as the basis for individual medical decisions. (That's what peer review, clinical trials, and FDA oversight are for!) Always consult your physician when making medical decisions.
