Abstract
Cell plasticity is important in development and tissue remodeling. Cells can sense physical and chemical cues from their local microenvironment and transduce the signals into the nucleus to regulate the epigenetic state and gene expression, resulting in a change in cell phenotype. In this review, we highlight the role of mechanical cues in regulating stem cell differentiation and cell reprogramming through the modulation of histone modifications. The effects of various mechanical cues, including matrix stiffness, mechanical stretch, and shear stress, on cell fate during tissue regeneration and remodeling will be discussed. Taken together, recent work demonstrates that the alterations in histone modifications by mechanical stimuli can facilitate epigenetic changes during cell phenotypic switching, which has potential applications in the development of biomaterials and bioreactors for cell engineering.
