WebJul 7, 2010 · The following paper tried to find out why Naked Mole Rats don’t get cancer [ Proc. Natl. Acad. Sci. vol. 112 pp. 1053 – 1058 ’15 ]. In tissue culture, naked mole rat fibroblasts show hypersensitivity to contact inhibition (aka early contact inhibition aka ECI). E.g. they stop dividing or die when they get too close to each other. WebApr 21, 2024 · At early times, when contact inhibition is weak, the colony grows exponentially in time, fully characterised by the proliferation rate. At long times, the colony boundary moves at a constant speed, determined only by the migration speed of a single cell and independent of the proliferation rate. Further, the model demonstrates how cell …
