 for six days, the CELL PICKER was used to pick cells and seed a 96-well
 plate. Then the same cultivation parameters were used to cultivate the
 seeded cells for six days, after which the cell adhesion and proliferation
 were checked. The operation process flow is illustrated in Fig. 1.  Button-operated

 Application Examples    Before picking  After picking

 • Picking for establishing iPS cells
 This confirmed that iPS cell colonies can be cultivated continuously
 while maintaining their undifferentiated state.
 • Collecting floating cell clusters (Spheroids)
 The system can also be used for the purpose of collecting spheroids   Fig. 2   Cell colonies before and after picking  Quality Control
