WebJan 8, 2024 · Work by Tian and colleagues (Tian et al., 2013) had previously demonstrated that a high molecular weight hyaluronic acid produced by naked mole rate fibroblasts contributes to early contact inhibition; the equivalent of a decrease in the population’s carrying capacity. This form of hyaluronic acid acts via the upstream Hippo component … WebSep 6, 2024 · Contact inhibition of locomotion (CIL) is a process whereby a cell ceases motility or changes its trajectory upon collision with another cell. CIL was initially characterized more than half a century ago and became a widely studied model system to understand how cells migrate and dynamically interact. Although CIL fell from interest for …

WebFeb 11, 2024 · The meaning of CONTACT INHIBITION is cessation of cellular movement, growth, and division upon contact with other cells. WebContact inhibition in human and mouse cells is mediated by the up-regulation of the cyclin-dependent kinase (Cdk) in-hibitor p27Kip1 (p27§). Early contact inhibition in naked mole rats was, how-ever, associated with the up-regulation of a different Cdk inhibitor, p16Ink4a (p16¶). Cells that bypassed early contact inhibition, either by ...
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 …
