Abstract
PC12 cells, which are derived from a rat pheochromocytoma, were independently patterned utilizing an impulsive force resulting in impulsive shockwave and cavitation bubble generation by focused femtosecond laser irradiation. Since the PC12 cells respond reversibly to nerve growth factor by induction of the neuronal phenotype, we can assess an influence that the impulsive force gives to the bioactivity in term of the cell differentiation. The patterned cells were accumulated on an intact dish and cultured for 3 days. The behavior of appearance and cell differentiation was observed by multipoint time-lapse system. On bases of these results, it was proved that the biological activity of the cell is unaffected by the femtosecond laser patterning.
