| Outline of Final Research Achievements |
Human induced pluripotent stem cells (hiPSCs) have the ability to differentiate into all types of cells. Letting many types of cells wander around culture dish could lead to out of control behavior, and there are still unknown differences in the movement of various cell types derived from hiPSCs.
In this study, we attempted to restrict the movement of hiPSCs to a specific pattern and to observe cell movement under multiple conditions simultaneously. We succeeded in creating a hair-thin (200 μm in diameter) circular pattern of hiPSCs. We also discovered that the early differentiating hiPSCs move slower than the undifferentiated hiPSCs.
The knowledge about cell movement and the development of the cell-movement regulation technique contribute to future regenerative medical applications.
