Abstract

original image

A thermally reversible culture substrate with a topographically active surface of aligned nanofibers is able to induce cytoskeletal alignment and nucleus elongation. These morphological changes induce myogenic differentiation in stem cells. The differentiated cells can be recovered in sheet form by thermally induced dissolution of the substrate. A surface able to provide topographical cues to create an aligned stem cell sheet, activated to differentiate to a specific lineage, can have a significant impact on engineering of tissue constructs for regenerative medicine applications.
