Living cells in tissues or biofilms communicate with neighboring cells through chemical and mechanical signals allowing them to organize spatially. To reduce the complexity of these natural systems we create synthetic tissues of non-living artificial cells. We use a microfluidic method to produce porous capsules with an artificial “nucleus” where DNA is immobilized. Upon addition of transcription and translation reagents capsules synthesize proteins, which localize to nuclei containing binding sites. Neighboring capsules communicate by producing transcription factors that diffuse through the artificial tissue suggesting that it can serve as a model system to study pattern formation.
