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 … WebThis polysaccharide provides early contact inhibition of cell division (anti-cancer effect). In addition, hyaluronan prevents the development of certain types of apoptosis, in particular, those induced by reactive oxygen species (ROS) (geroprotective effect preventing ROS-induced decrease in cellularity in the organs and tissues of aging ...
WebNational Center for Biotechnology Information WebFurthermore, uncontrolled growth because of the loss of contact inhibition of proliferation is a hallmark of solid tumors (3, 4). Despite these insights, the underlying regulatory mechanisms of the contact inhibition of proliferation remain poorly understood, although cadherin-mediated cell–cell adhesion is thought to play an important role (2).
WebFeb 2, 2024 · Early contact inhibition is due to unusually long versions of hyaluronic acid (HA), which is the main non-protein component in the extracellular matrix. Early contact inhibition may be replicated in humans by lengthening HA (Seluanov et al. 2024). Interestingly, Seluanov and Gorbunova found “a very promising molecule that increases … 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]. On the other hand, we previously showed that NMR iPS cells have a lower proliferative capacity than mouse iPS cells . In this study, we revealed that ...
