RT Journal Article SR Electronic T1 Overview: Modeling Heterogeneous Tumor Tissue as a Multiphase Material JF bioRxiv FD Cold Spring Harbor Laboratory SP 031534 DO 10.1101/031534 A1 Frieboes, Hermann B. YR 2015 UL http://biorxiv.org/content/early/2015/11/12/031534.abstract AB Tumors are typically heterogeneous tissues comprised of multiple cell species in addition to extra-cellular matrix (ECM) and water fluid. It is difficult to model these components at the tissue (10−3–10−2m) scale, where individual cells cannot be represented without prohibitive computational burden. Assuming that same-kind components tend to cluster together, a multiphase approach can be applied to represent heterogeneous tumor tissue at this larger physical scale. This method enables simulating mixture of elements within tissues, e.g., geno-/phenotypic heterogeneity underlying mutation- or microenvironment-driven tumor progression. Further, by not explicitly tracking interfaces, this methodology facilitates realistic modeling of tissue in 3-D.
