Hydrogel-Based Nanocomposites and Mesenchymal Stem Cells: A Promising Synergistic Strategy for Neurodegenerative Disorders Therapy

Small amplitude oscillatory shear tests. After the preparation, small amplitude oscillatory shear tests were performed on acellular and cell-laden (0.5·106 cells/mL gel) PEG/Carbomer-based hydrogels at 37°C with frequency ranging from 0.01 to 10 Hz. Both acellular and cell-laden materials showed a gel-like behaviour as the storage modulus G′ was greater than the loss modulus G′′ in the frequency range investigated. In particular, G′ was almost constant for both acellular gels (227.5 ± 34.1 Pa) and cell-laden constructs (280.0 ± 41.0 Pa).
