WebA tumor spheroid is a spherical mass of cancer cells with a diameter of approximately 400 μm, which contains tens of thousands of cells (one estimate shows 7 × 10 4 cells). These three-dimensional tumor spheroids are useful as cancer models because they more closely resemble the state of actual cancer than two-dimensional cultured cells. In living tissue, cells exist in 3D microenvironments with intricate cell-cell and cell-matrix interactions and complex transport dynamics for nutrients and cells. Standard 2D, or monolayer, cell cultures are inadequate representations of this environment, which often makes them unreliable predictors of in vivo drug efficacy and toxicity. 3D spheroids more closely resemble in vivo tissue in terms of cellular communication and the development of extracellular matrices. The…
