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

Nature 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.

Hydrogel viscoelasticity modulates migration and fusion of mesenchymal stem cell spheroids

Bioengineering & 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 ...

Tuning Viscoelasticity in Alginate Hydrogels for 3D Cell Culture Studies

Current Protocols, 2021
Physical properties of the extracellular matrix (ECM) affect cell behaviors ranging from cell adhesion and migration to differentiation and gene expression, a process known as mechanotransduction.

Viscoelasticity Acts as a Marker for Tumor Extracellular Matrix Characteristics

Frontiers in Cell and Developmental Biology, 2021
Biological materials such as extracellular matrix scaffolds, cancer cells, and tissues are often assumed to respond elastically for simplicity; the viscoelastic response is quite commonly ignored.

Viscoelastic modeling of the stress relaxation behavior for the bionic extracellular matrix polymer scaffold

Medicine in Novel Technology and Devices, 2022
Viscoelasticity of the extracellular matrix (ECM) plays a critical part in controlling cell behavior. However, the structure-related viscoelasticity of the synthetic ECM and its mechanism are rarely reported.

Investigation of the Viscoelastic Effect on Optical- Fiber Sensing and Its Solution for 3D-Printed Sensor Packages [PDF]

, 2019
Viscoelasticity is an effect seen in a wide range of materials and it affects the reliability of static measurements made using Fiber Bragg Grating-based sensors, because either the target structure, the adhesive used, or the fiber ...

Magnetic microrheometry of tumor-relevant stiffness levels and probabilistic quantification of viscoelasticity differences inside 3D cell culture matrices.

PLoS ONE, 2023
The progression of breast cancer involves cancer-cell invasions of extracellular matrices. To investigate the progression, 3D cell cultures are widely used along with different types of matrices.
