Piezo1 regulates the mechanotransduction of soft matrix viscoelasticity [PDF]
Mechanosensitive ion channels such as Piezo1 have fundamental roles in sensing the mechanical properties of the extracellular matrix. However, whether and how Piezo1 senses time-dependent matrix mechanical properties, that is, viscoelasticity, remains ...

Distinguishing thixotropy from viscoelasticity [PDF]
Owing to non-linear viscoelasticity, materials often show characteristic features that resemble those of thixotropy. This issue has been debated in the literature over the past several decades, and several experimental protocols have been proposed to ...

Hydrogel viscoelasticity modulates migration and fusion of mesenchymal stem cell spheroids
Multicellular spheroids made of stem cells can act as building blocks that fuse to capture complex aspects of native in vivo environments, but the effect of hydrogel viscoelasticity on cell migration from spheroids and their fusion remains largely ...
