We developed a dynamic cell culture platform with dynamically tunable nano-roughness and elasticity. Temperature-responsive poly(e-caprolactone) (PCL) films were successfully prepared by crosslinking linear and tetra-branched PCL macromonomers. By optimizing the mixing ratios, the crystal-amorphous transition temperature (T-m) of the crosslinked film was adjusted to the biological relevant temperature (33 degrees C). While the crosslinked films are relatively stiff (50 MPa) below the T-m, they suddenly become soft (1 MPa) above the T-m. Correspondingly, roughness of the surface was decreased from 63.4-12.4 nm. It is noted that the surface wettability was independent of temperature. To investigate the role of dynamic surface roughness and elasticity on cell adhesion, cells were seeded on PCL films at 32 degrees C. Interestingly, spread myoblasts on the film became rounded when temperature was suddenly increased to 37 degrees C, while significant changes in cell morphology were not observed for fibroblasts. These results indicate that cells can sense dynamic changes in the surrounding environment but the sensitivity depends on cell types.
