Colon_Crypt_Model_073120.nlogo

Computer program that simulates and plots the dynamics of stem cells, transient amplifying cells, differentiated cells, and mutant cells in normal human colon crypts and early colon cancer. It has been calibrated with measurements of human biopsy specimens. Includes graphical user interface, detailed information text, and annotated code. Experiments can be run from the GUI without knowledge of coding, or from the Behavior Space Tool using example code or modified code. Has been used to simulate human colon cancer initiation, therapy, and prevention.Different chemotherapy or prevention intermittent dose schedules can be input. Chemotherapy of heterogeneous and drug resistant early colon cancers can be simulated. Circadian cell proliferation can be selected to investigate chronomodulated chemotherapy dose schedules. Simulated output can be saved in spreadsheet format, or as images of plots of cell numbers as function of time. It runs on the open-source multi-platform NetLogo application version 5.3.1 available at https://ccl.northwestern.edu/netlogo/index.shtml. Described in the following publications: Theoret Biol Med Model. 2013;10:66-89. Cancer Chemother Pharmcol 2017;79:889-898. Converg Sci Phys Oncol 2017;3:035004. Cancer Inform 2019;18:1-8. JCO Clin Cancer Inform 2020;4:514-520. A forthcoming publication will describe results of circadian-timed chemotherapy.To download the computer program click on the red link “Download file" to the left.
