Early contact inhibition

WebDec 25, 2024 · 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. Inactivation of both p53 … 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 …

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. As motile cells come into contact in confluent cultures, they exhibit decreased mobility and mitotic activity … WebNov 1, 2024 · Proliferation of NMR skin fibroblasts is reportedly suppressed by induction of early contact inhibition via INK4A activation due to signaling of high molecular mass hyaluronan [10, 40].
