Microfiber platform for oligodendrocyte myelination by Ong, William

“…We demonstrated that increasing structural stiffness promotes oligodendrocyte precursor differentiation, which was validated with conventional two-dimensional tunable stiffness hydrogels. Moreover, for the first time, we demonstrated with our artificial axonbased tunable stiffness, that an increase in structural stiffness impedes oligodendrocyte myelination. …”

Time-resolved linear and non-linear rheology of thixotropic and aging complex fluids: Application to particulate and biopolymeric physical gels by John Rathinaraj, Joshua David

“…Temporal changes in microstructure and relaxation dynamics are ubiquitously observed in materials such as hydrogels, food products and drilling fluids. These materials are in general known as mutating materials and the build-up or breakdown of microstructure is commonly both time– and shear-rate (or shear-stress)–dependent resulting in a range of complex phenomena collected under the term thixotropy. …”
