Cell manipulation by nodal circle resonance vibration of a cell cultivation substrate

In this paper, we propose a novel cell culture method to generate an organ without scaffold. The concept of our study is to apply the principle of Chladni´s figures in cell manipulation. To confirm this concept, we developed cell cultivation device that can excite resonance vibration of the cell cultivation substrate. After the fabrication of the device, we estimated the resonance frequency and vibration amplitude distribution of our device. Since the fabricated device successfully produced the designed vibration mode, we conducted cell manipulation experiment to confirm our concept. In our experiment, we varied the initial number of cells that were seeded into our device. Cells were manipulated by resonance vibration for 120 min. After the manipulation, we checked cell distribution on the substrate. As a result, cells were successfully manipulated by the resonance vibration when the initial number of cells was appropriate.
