It Takes Two to Tango: Controlling Human Mesenchymal Stromal Cell Response via Substrate Stiffness and Surface Topography: Controlling Human Mesenchymal Stromal Cell Response via Substrate Stiffness and Surface Topography

Cells sense extracellular matrix-induced biophysical signals, which are transduced into intracellular signaling cascades, and trigger a series of cell responses, including adhesion, migration, and lineage commitment. Traditionally, in in vitro context, monofactorial approaches are employed to control cell fate, despite the fact that in vivo cells are exposed simultaneously to a diverse range of signals. Herein, an overview of key mechanotransduction pathways is first provided. Conventional single-factor and contemporary multifactorial methodologies, based on substrate rigidity and surface topography, are then reviewed to recapitulate in vitro the in vivo niche, in an attempt to elucidate the underlying mechanisms involved in human mesenchymal stromal cell-material interactions. Cells sense extracellular matrix-induced biophysical signals, which are transduced into intracellular signaling cascades, and trigger a series of cell responses, including adhesion, migration, and lineage commitment. Herein, key mechanotransduction pathways associated with surface topography and substrate stiffness in mesenchymal stromal cells culture are discussed.image (c) 2023 WILEY-VCH GmbHCells sense extracellular matrix-induced biophysical signals, which are transduced into intracellular signaling cascades, and trigger a series of cell responses, including adhesion, migration, and lineage commitment.
