Abstract
Biophysical factors such as mechanical cues and micro/nano features of extracellular matrix regulate a variety of cell functions, including signal transduction from the cell surface to nucleus. Recent studies indicate that biophysical factors not only modulate immediate mechanotransduction and signaling, but also exert long-term effects on phenotypic changes, including stem cell differentiation and cell reprogramming. Both cell differentiation and reprogramming involve epigenetic state changes such as DNA methylation and histone methylation and acetylation, each of which affects gene expression independent of DNA sequence. There is emerging evidence that biophysical factors, in addition to transcriptional factors and biochemical factors, can regulate the epigenetic state of the cells and thus its phenotypic changes. This chapter will highlight the potential mechanisms through which mechanotransduction may lead to epigenetic modifications.
