High throughput fabrication of cell spheroids by templating water-in-water Pickering emulsions

We report a simple technique for the high throughput generation of tissue spheroids based on the encapsulation of dispersed adherent cells in particle-stabilised water-in-water emulsions. We demonstrate cell encapsulation and spheroid generation using fibroblast cells which can find applications in 3D culturing, tissue engineering, inks for bioprinting and cell therapy.
