Mechanical oscillations at the cellular scale
WebJan 5, 2024 · Plants spend most of their life oscillating around 1-3 Hz due to the effect of the wind. Therefore, stems and foliage experience repetitive mechanical stresses through these passive movements. However, the mechanism of the cellular perception and transduction of such recurring mechanical signals remains an open question. WebHere we discuss mechanical oscillations generated by active systems in cells. Examples are oscillatory regimes in muscles, the periodic beating of axonemal cilia and flagella and …

WebMay 17, 2024 · The use of a mechanically oscillating substrate should be effective, but requires equipment for stretching the substrate and special incubators. Thus, from a practical viewpoint, we used a method that takes advantage of spontaneous cell migration. WebMorphological changes during development, tissue repair, and disease largely rely on coordinated cell movements and are controlled by the tissue environment. Epithelial cell sheets are often subjected to large-scale deformation during tissue formation. The active mechanical environment in which epithelial cells operate have the ability to promote …

One example is provided by the oscillations of nuclei in the fission yeast Schizosaccharomyces pombe prior to meiosis. There, microtubules are drawn along the cell wall by dyneins ( Vogel et al ., 2009 ).
Weboscillations have also been observed during asymmetric cell divisions. In this case, the spindle poles exhibit periodic motion and it has been proposed that this phe-nomenon results from an interplay between astral micro-tubules and cortical force generators [7,8,9 ]. Mechanical oscillations can be of direct importance for
