Smar to ordinary epthelal cells, PrCa cells caalso actvely nvade the surroundng matrgel, despite the fact that ther mode of mgratos dfferent from your normal, collectve sheet or tube mgratopatterns observed branchng of standard cells.The phenotype of cancer nvasodepends ocompostoand densty with the ECM, and cavary from amoebod blebbng, mesenchymal fbroblast lke motty and multcellular streamng or chamgraton.Naturally, the nvasve potental also depends othe genetc background within the PrCa cells and ther capabty to engage strngent epthelal cell cell contacts.Mammary and various epthelal cancer cells type cylndrcal, spndle lke cells wth the potental to contract and elongate, supportng mgratothrough the surround ng ECM mesh.A great deal less s knowabout PrCa.nvasos asssted by proteolytc processes and proteases like cathepsns, matrx metalloprotenases, soluble components secreted by fbroblasts or even the presence of fbroblasts themselves, as well as other components such as fbronectand lysyl oxdases.
