Studying Cancer Cell Behavior in Three-Dimensional Culture Systems
Three-dimensional (3D) cell culture systems have been used to study the functional interactions between epithelial cells and the extracellular matrix (ECM). The establishment of apicobasal polarity in such models promotes cell survival in response to various apoptotic stimuli, and the absence of interactions with the ECM induces apoptosis of cells in the interior of the 3D structures and lumen formation. Perturbation of proliferation and survival signals can lead to loss of lumen formation, an early event in epithelial carcinogenesis. See text for details.
