Early contact inhibition

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 ...

WebOct 26, 2009 · Contact inhibition is a key anticancer mechanism that arrests cell division when cells reach a high density. In cell culture, naked mole-rat fibroblasts arrest at a much lower density than those from a mouse. We demonstrate that early contact inhibition requires the activity of p53 and pRb tumor suppressor pathways.

WebApr 12, 2024 · Contact inhibition is a regulatory mechanism that functions to keep cells growing into a layer one cell thick (a monolayer). If a cell has plenty of available substrate space, it replicates rapidly and moves freely. This process continues until the cells occupy the entire substratum. At this point, normal cells will stop replicating. WebContact Inhibition.
