摘要: Mammalian cells respond to their substrates by complex changes in gene expression profiles, morphology, proliferation and migration. We report that substrate nanotopography alters morpohology of human embryonic stem (hESCs). Fibronectin-coated poly(di-methyl siloxane) with line-grating (600nm ridges 600nm spacing 600+/-150nm feature height) induced hESC alignment elongation, mediated the organization cytoskeletal components including actin, vimentin, alpha-tubulin, reduced proliferation. Spatial polarization gamma-tubulin complexes was also observed response nanotopography. Furthermore, addition actin disrupting agents attenuated proliferative effects These findings further demonstrate importance interplay between cytoskeleton interactions as a key modulator morphological cellular hESCs on
