Modeling multiple taxis: Tumor invasion with phenotypic heterogeneity, haptotaxis, and unilateral interspecies repellence

نویسندگان

چکیده

We provide a short review of existing models with multiple taxis performed by (at least) one species and consider new mathematical model for tumor invasion featuring two mutually exclusive cell phenotypes (migrating proliferating). The migrating cells perform nonlinear diffusion types in response to non-diffusing cues: away from proliferating up the gradient surrounding tissue. Transitions between subpopulations are influenced subcellular (receptor binding) dynamics, thus conferring setting multiscale character. prove global existence weak solutions simplified version numerical simulations full under several phenotype switching motility scenarios. We also compare (via simulations) this corresponding haptotaxis-chemotaxis indirect chemorepellent production discussion about possible extensions challenges.

Human Cancer Modeling: Recapitulating Tumor Heterogeneity Towards Personalized Medicine

Despite diagnostic, preventive and therapeutic advances, growing incidence of cancer and high rate of mortality among patients affected by specific cancer types indicate current clinical measures are not ideally useful in eradicating cancer. Chemoresistance and subsequent disease relapse are believed to be mainly driven by the cell-molecular heterogeneity of human tumors that necessitates perso...

Phenotypic heterogeneity in modeling cancer evolution

The unwelcome evolution of malignancy during cancer progression emerges through a selection process in a complex heterogeneous population structure. In the present work, we investigate evolutionary dynamics in a phenotypically heterogeneous population of stem cells (SCs) and their associated progenitors. The fate of a malignant mutation is determined not only by overall stem cell and non-stem c...

Tumor Invasion Optimization by Mesenchymal-Amoeboid Heterogeneity

Metastasizing tumor cells migrate through the surrounding tissue and extracellular matrix toward the blood vessels, in order to colonize distant organs. They typically move in a dense environment, filled with other cells. In this work we study cooperative effects between neighboring cells of different types, migrating in a maze-like environment with directional cue. Using a computerized model, ...

Intratumoral phenotypic heterogeneity as an encourager of cancer invasion.

We present a novel in vitro breast tumor model to mimic intratumoral phenotypic heterogeneity based on a microfluidic system incorporating ECM scaffolds capable of providing a physiologically relevant tumor microenvironment. To study the regulation of invasive potentials by intratumoral subpopulation conditions, we developed heterogeneous cancer cell subpopulations by co-culturing two breast ca...
