Drug Resistance Model (2013 WhAM workshop)

This is a part of a project conducted at the WhAM! Wokshop at the IMA in Minneapolis in September 2013.
This set of Matlab-based exercises allows to test different mechanisms of cell resistance (pre-existing and acquired) to anticancer drugs.
Created by WhAM! Team: K.A. Rejniak, J. Gevertz, K.A. Norton, A. Volkening, J. Perez-Velazquez and Z. Aminzare.
The exercises below guide a user in how to reproduce simulations summarized in Figure 1 of our work published in a book "Applications of Dynamical Systems in Biology and Medicine" that can be find here.

Clonogenic Assay Model (ICBP grant & Miles for Moffitt Award)

This project is partially supported by the NIH-ICBP grant, and partially by the Miles for Moffitt Milestone Award.
Created by MJ. Kim
  1. Routine "CellCulture" allows to examine the impact of cell motility on the formation of cell clusters in 2D cell cultutre model; the above images were generated for motility of 1, 10 or 100, repectively: CellCulture.m CellCulture.zip
  2. This is a companion code generating results shown in Fig.5 "Collective behavior and spatial organization of cells with different motilities from amanuscript: Kim M, Reed D, Rejniak KA.

Tumor Growth Model (2010 MBI Cancer Modeling Bootcamp)

This is a part of the Cancer Modeling Bootcamp for the Biologists organized by the MBI in September 2010.
This set of Matlab-based exercises shows step-by-step how an agent-based model can be used to investigate growth of a tumor colony.
Created by K.A. Rejniak
  1. Handouts containing model description and exercise instructions can be find here: Handouts
  2. Exercise 1, "Tumor Growth": allows to examine how growth of the whole tumor cluster depends on individual cell doubling time: Ex1.m
  3. Exercise 2, "Go or Grow": allows to examine how cell proliferating and moving capabilities contribute to the growth of the whole tumor cluster: Ex2.m, ParamSpace.m
  4. Exercise 3, "Cell Metabolism", allows to examine how tumor colony will change in response to microenvironmental factors, such as nutrient gradient: Ex3.m
  5. Exercise 4, "Cell Mutations", allows to examine how tumor cell heterogeneity defined in terms of cell responses to the microenvironmental factors influence the behavior of teh whole tumor - here 6 clones of mutated cells are traced: Ex4.m
  6. Exercise 5, "All-in-one", this routine combines all features discussed previously and allows to define all properties for a tumor cell base line and the mutants: Ex5.m
  7. Exercise 6, "3D Tumor Growth", all discussed previously concepts are applied to the 3D cellular automata model: Ex6.m

Deformable Cell Model besd on the Immersed Boundary Method

~ IBCell (Institute for Advanced Studies 2002)

 

This is a part of a hands-on excercise session prepared for the postgraduate lecture series in the Program for Women in Mathematics on Mathematical Biology held at the Institute for Advanced Study in Princeton, in May 2003.
This set of Matlab-base excersices shows step-by-step how the interactions between the fluid and the immersed body are defined in the immersed boundary method -- here applied to a growing cell of either circular or squared shape with a pseudo-skeleton imposed by spring forces.
Created by K.A. Rejniak
  1. Routine "CellGrowth"illustrates the way the immersed boundary method is implemented (each step is shown above):
    • a cell is composed from boundary points that form either a circle or a square (row 1, column 1);
    • the adjacent boundary points are connectd by springs to form cell membrane; additional springs are defined to form a pseudo-cytoskeleton (row 1, column 2);
    • springs that are not in a resting distance exert forces on the boundary points (row 1, column 3);
    • these forses are transmitted to the fluid (row 2, colum 1);
    • the fluid flow arising form the centrally located fluid source and all boundary and cytoskeletal forces is computed (row 2, column 2);
    • fluid flow velocities are extrapolate to all boundary points (raw 2, column 3).
