Effects of actuation of nanoporous gold on cell orientation in a fibroblast sheet.


ABSTRACT: Mechanical stimulation such as flood flow often plays a vital role in the growth and maintenance of a living body, and it is important to investigate cell responses to mechanical stimulation. To date, cell responses to mechanical stimulation have been investigated in detail. However, the cell responses have been little known in a cell sheet. In the present study, a small cyclic strain (CS) of ~0.5% generated by a nanoporous gold actuator was loaded on a cell sheet of fibroblasts, and the effects of the CS on cell orientation were investigated. Individual cells were randomly distributed after the CS application, whereas cells were oriented in a specific direction after the CS application for the cell sheet. Thus, the CS had a different effect on the cell sheet from that on the individual cells. It is suggested that the cadherin/p-120 catenin complex played an important role in the cell response to mechanical stimulation in a cell sheet.
