Motility Control of Neuronal and Human iPS Cells under Serum - and Feeder - Free Culture Condition

2 Cell movement is an important step in development. Two experiments were conducted to investigate cell movement control in serumand feeder-free conditions. There were two key findings. 1) The direction of cell migration was affected by the use of a ratchet-shaped micro-chamber. 2) Two proteins were needed as a coating to make the human iPS cell pattern. These findings provide useful tools for a basic study on cell migration and an applied one on regenerative medicine.
