Supplementary Figure S2. High-throughput phenotyping of cell-to-cell interactions in gel microdroplet pico-cultures

Schematic for cultivation chamber. The cultivation chamber was fabricated and sterilized as described for the microfluidic droplet generator chip (Figure 2 legend). The microfluidic cultivation chamber was used to microscopically visualize droplets without disturbing them or sacrificing viability, as well as providing an even distribution of light.
