Development of a Droplet Microfluidic Assay for Radiotherapy Treatment of Multicellular Spheroids

چکیده
In this study, we report the development of a droplet microfluidic assay for the formation and radiotherapy treatment of multicellular spheroids. Glioma cells formed multicellular spheroids following their encapsulation within biocompatible medium-in-fluorinated oil (M/O) droplets with a non-adherent surfactant interface. Our studies identified that the ratio of volume-of-medium to number-of-cells and the refreshment of medium are important parameters for healthy spheroid growth within M/O droplets. In addition, a protocol was validated to extract radiotherapy dose responses from the spheroids based on their size variation via brightfield microscopy.
