Fluorescent imaging of primary human BMECs in the original versus new NVU design. Images were acquired 3 days after seeding and are representative of multiple devices. The transition from a polycarbonate membrane in the original NVU to a PET membrane (which is thinner and more optically transparent) in the updated NVU improves the ability to image cells in real-time
