Mechanotransduction and Biophysical Regulation
Biochemical and biological factors are not the only key players in cell sensing, signal transduction and epigenetic regulation. Biophysical cues, such as mechanical forces, electrical signals, and micro/nano structures, play an equally important role. Our research goal is to gain a deeper understanding of these processes through the mechanisms of mechanotransduction and biophysical regulation, and to apply this knowledge to develop new technologies for engineering cell fate and promoting tissue regeneration. Our ongoing studies are focused on the following areas: (1) investigating the impact of mechanical forces on cell sensing, epigenetic state, and 3D chromatin reorganization, and (2) exploring the potential of electrical modulation for promoting neuromuscular regeneration.
