Healthy tissues are like healthy ecosystems: Both composed of diverse populations. But in tumors, a single, malignant cell type often dominates. A new computer model is helping researchers understand why, and it could pave the way to more effective cancer treatments.
Using mathematical algorithms, a team of researchers has developed a new, 3D simulation depicting how a tumor grows from a handful of rogue cell types (represented by different colors) into a malignant mass comprised of millions of cancerous mutants. The model, published this week in Nature, is reinforcing something that laboratory studies have also shown: Tiny movements of cells within a tumor can cause the mass to quickly expand, or allow it to rebound after chemotherapy.
