Piezo1 regulates the mechanotransduction of soft matrix viscoelasticity [PDF]

open access: yesNature Communications
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 ...

Time Steps Expandable Inverse Model for Ultrasound Shear Wave Elastography Imaging [PDF]

open access: yesJournal of Medical Physics
Aim: Ultrasound shear wave elastography (USWE) is a noninvasive imaging technique developed in the last two decades for clinical diagnosis. Commercialized tools of USWE perform imaging by measuring tissue elasticity.

Dynamic Hydrogels with Viscoelasticity and Tunable Stiffness for the Regulation of Cell Behavior and Fate

open access: yesMaterials, 2023
The extracellular matrix (ECM) of natural cells typically exhibits dynamic mechanical properties (viscoelasticity and dynamic stiffness). The viscoelasticity and dynamic stiffness of the ECM play a crucial role in biological processes, such as tissue ...

Programmable viscoelasticity in protein-RNA condensates with disordered sticker-spacer polypeptides

open access: yesNature Communications, 2021
Liquid-liquid phase separation of multivalent proteins and RNAs drives the formation of biomolecular condensates that facilitate membrane-free compartmentalization of subcellular processes.

Distinguishing thixotropy from viscoelasticity [PDF]

open access: yesJournal of rheology, 2021
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

open access: yesBioengineering & Translational Medicine, 2022
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 ...
