Algae Breathes Life Into 3D-Printed Tissues

Imagine if human tissue could harness the power of plants and generate oxygen through photosynthesis. If it sounds like a creature that came out of a lab, that’s because it is. Harvard researchers published research based on 3D-printed tissue models of liver cells Wednesday that derive oxygen from Chlamydomonas reinhardtii, single-celled algae.
