Abstract
Accumulatively, cellular behaviours triggered by biochemical cues have been widely explored and the focus of research is gradually shifting to biophysical cues. Compared to physical parameters such as stiffness, substrate morphology and viscoelasticity, the influence of viscosity on cellular behaviours is relatively unexplored and overlooked. Thus, in this study, the influence of viscosity on the adipogenic and osteogenic differentiation of human mesenchymal stem cells (hMSCs) was investigated by adjusting the viscosity of the culture medium. Viscosity exhibited different effects on adipogenic and osteogenic differentiation of hMSCs during two-dimensional (2D) culture. High viscosity facilitated osteogenic while inhibiting adipogenic differentiation. During adipogenic differentiation, the effect of viscosity on cell proliferation was negligible. However, during osteogenic differentiation, high viscosity decreased cell proliferation. The different influence of viscosity could be explained by the activation of mechanotransduction regulators of Yes-associated protein (YAP) and β-catenin. High viscosity could promote YAP and β-catenin nuclear translocation during osteogenic differentiation, which was responsible for the increased osteogenesis. High viscosity inhibited adipogenesis through promoting YAP nuclear translocation. This study could broaden the understanding of how viscosity can affect stem cell differentiation during 2D culture, which is valuable for tissue engineering.

A novel mechanoeffector role of fibroblast S100A4 in myofibroblast transdifferentiation and fibrosis. J Biol Chem 2024; 300:105530.

Abstract
Fibroblast to myofibroblast transdifferentiation mediates numerous fibrotic disorders, such as idiopathic pulmonary fibrosis (IPF). We have previously demonstrated that non-muscle myosin II (NMII) is activated in response to fibrotic lung extracellular matrix, thereby mediating myofibroblast transdifferentiation. NMII-A is known to interact with the calcium-binding protein S100A4, but the mechanism by which S100A4 regulates fibrotic disorders is unclear. In this study, we show that fibroblast S100A4 is a calcium-dependent, mechanoeffector protein that is uniquely sensitive to pathophysiologic-range lung stiffness (8-25 kPa) and thereby mediates myofibroblast transdifferentiation. Re-expression of endogenous fibroblast S100A4 rescues the myofibroblastic phenotype in S100A4 KO fibroblasts. Analysis of NMII-A/actin dynamics reveals that S100A4 mediates the unraveling and redistribution of peripheral actomyosin to a central location, resulting in a contractile myofibroblast. Furthermore, S100A4 loss protects against murine in vivo pulmonary fibrosis, and S100A4 expression is dysregulated in IPF. Our data reveal a novel mechanosensor/effector role for endogenous fibroblast S100A4 in inducing cytoskeletal redistribution in fibrotic disorders such as IPF.

Abstract
Matrix stiffness has been disclosed as an essential regulator of cell fate. However, it is barely studied how the matrix stiffness affects stem cell functions when cell morphology changes. Thus, in this study, the effect of hydrogel stiffness on adipogenic differentiation of human bone-marrow-derived mesenchymal stem cells (hMSCs) with controlled morphology was investigated. Micropatterns of different size and elongation were prepared by a photolithographical micropatterning technique. The hMSCs were cultured on the micropatterns and showed a different spreading area and elongation following the geometry of the underlying micropatterns. The cells with controlled morphology were embedded in agarose hydrogels of different stiffnesses. The cells showed a different level of adipogenic differentiation that was dependent on both hydrogel stiffness and cell morphology. Adipogenic differentiation became strong when the cell spreading area decreased and hydrogel stiffness increased. Adipogenic differentiation did not change with cell elongation. Therefore, cell spreading area and hydrogel stiffness could synergistically affect adipogenic differentiation of hMSCs, while cell elongation did not affect adipogenic differentiation. A change of cell morphology and hydrogel stiffness was accompanied by actin filament alignment that was strongly related to adipogenic differentiation. The results indicated that cell morphology could affect cellular sensitivity to hydrogel stiffness. The results will provide useful information for the elucidation of the interaction of stem cells and their microenvironmental biomechanical cues.
