| Outline of Final Research Achievements |
This project aimed to investigate 3D invasion process of glioma stem cells (GSCs) coculturing with endothelial cells (ECs) using a microfluidic device. In particular, we focused on microenvironmental factors such as differentiation status of GSCs, interstitial flow, and interactions with blood vessels, to investigate control factors of GSC invasion. Our results revealed following things. 1) GSCs in differentiation conditions significantly responded to interstitial flow application compared with those in stem cell conditions. 2) GSCs extended characteristic protrusions downstream of interstitial flow, resulting in an increased invasion distance. 3) GSCs acquired invasion activity in the presence of ECs.
