Cell spreading and migration play a pivotal role in many diseases such as tumor metastasis. In particular, nasopharyngeal tumor cells have known of their tendency of migration to pterygoid muscles and further distant metastasis. Although existing studies revealed key characteristics of the nasopharyngeal tumor cells, their migration preference is yet to be thoroughly understood, especially in the physical aspects including the microtopographical factors. Researchers have developed techniques in recent years to study microtopography-related cell behaviors but they are not yet applied in investigating the nasopharyngeal tumor cells. In this work, we elaborate the spreading and migration characteristics of normal and cancerous nasopharyngeal cells on micrograting substrates mimicking the microtopography of myotubes of the pterygoid muscles. We further apply interference reflection microscopy (IRM) to visualize the cell-substrate adhesion dynamics. We are interested in examining the microtopography-related cell spreading and migration behaviors and their correlations, providing insights for deeper understanding and more promising prediction on the nasopharyngeal tumor metastasis.
