Cell migration in 3D ECM Review article Tumor-cell invasion and migration: diversity and escape mechanisms Nature Review 2003 (3) 362-374
Many studies confirm that the multistep model of cell migration applies to cancer cells. ECM-degrading enzymes, such as matrix metalloproteinases (MMPs) are frequently up-regulated in tumor cells, and facilitate migration in vitro, as well as dissemination and metastasis in vivo. The over-expression or activation of the Rac, Rho, ROCK or MLCK signaling pathways have been correlated with in vitro tumor cell migration, as well as in vivo invasion and progression. Pharmacological inhibitors that block integrins, MMPs, ROCK or MLCK are being developed to interfere with cancer-cell invasion.
* Intercellular junctional complex apical basal
Cell-cell adhesionresults from interaction between extracellular domains of cadherins from opposing cellsto form a "cell adhesion zipper", which, if extensive, would hold cells together with great strength different cell types might engage in different types of interactions The greater the number of interacting cadherins in a cluster, the greater the strength of adhesion between apposing cells
Embryonic development is characterized by changes in gene expression, cell shape, cell motility, cell adhesion, etc. * mesenchymal-epithelial transition Mesenchyme (loose, primarily nonadhesive cells) N-cadherin Epithelium (tightly adherent, organized cell layer)
Sites of EMT and MET in the emergence and progression of carcinoma. Nature, Vol. 2, 442-454
The morphological transition of EMT was accompanied by scattering and directional migration toward serum factors, a gain of mesenchymal cell markers (fibronectin, vimentin, and N-cadherin), and a loss of epithelial markers (E-cadherin, and a- and g-catenin).
