| Outline of Final Research Achievements |
The aim of this study was to evaluate metabolic changes in cultured vascular endothelial cell remodeling using a combined technique of inverted fluorescence microscopy and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). For this purpose, a composite film with excellent light transmittance and conductivity was prepared, consisting of indium tin oxide (ITO) and poly (dimethyl siloxane) (PDMS). Cell patterning could be applied to the fabricated composite film surface. Furthermore, vascular endothelial cells（ECs）cultured on the composite film showed mechanical response to flow. It was also found that the composite film can be used as a sample plate for MALDI-TOF-MS. In summary, our group constructed a complex experimental system for the patterned ECs subjected to shear stress.
