Table 1.
Type of Model | Characteristic Being Tested | Results Influenced by the Characteristic | Reference |
---|---|---|---|
Experimental | ECM stiffness | lineage dependent on stiffness | 9, 21, 32, 65 |
cocultured cells | lineage dependent on cocultured cells | 66, 67 | |
MMP activity | inhibition of MMP activity results in reduced speed and persistence of cell movement | 40 | |
Computational | MMP activity | inhibition of MMP activity results in reduced speed and persistence of cell movement | 28 |
uPA activity | cell invasion result of chemotactic and haptotactic reactions | 2 | |
proliferation, angiogenesis | necrotic core within tumor, high microvascular density at periphery | 12 | |
proliferation, migration | cancer cells with aggressive phenotypes preferentially migrate | 8 | |
migration, chemotaxis | hypoxia and heterogeneous ECM result in more aggressive tumor cells | 3, 4 | |
oxygen, nutrient levels | subpopulation preferentially accounts for tumor growth | 34 |
ECM, extracellular matrix; MMP, matrix metalloproteinase; uPA, urokinase-type plasminogen activator.
