| Outline of Final Research Achievements |
Honeycomb patterned scaffolds have been fabricated by casting solutions of polybutadiene (PB) and polystyrene (PS) containing amphiphiles under humid conditions. Flat films of these materials were also prepared as reference films. By irradiation of UV light, PB honeycomb and flat scaffolds were cross linked. By using an atomic microscope, surface modulus of each sample has been measured. The measurement revealed that surface modulus increased by UV irradiation. Human mesenchymal stem cells were cultured on these scaffolds and we found that adhesion and differentiation of human mesenchymal stem cells were modulated by changing scaffold parameters including surface modulus and pore sizes. These results will open a path to a new development on controlling behavior of stem cells.
