RESUMO
Cell viability and cell migration capacities are critical parameters for cell culture-related studies. It is essential to monitor the dynamic changes of cell properties under various co-culture conditions to our better understanding of their behaviours and characteristics. The real time cell analyzer (RTCA, xCELLigence, Roche) is an impedance-based technology that can be used for label-free and real-time monitoring of cell properties, such as cell adherence, proliferation, migration and cytotoxicity. The practicality of this system has been proven in our recent cancer studies. In the present method, we intend to use co-cultures of pancreatic cancer cells (HP62) and mesenchymal stem cells to describe in detail, the procedures and benefits of RTCA.
