  "abstract": "Epithelial cells can resemble nematic liquid crystals, exhibiting long-range alignment and topological defects. Bera et al. show that these defects do not arise randomly but that they are pre-patterned by coordinated cell forces and motions. Some of these defects can move in both directions within the same tissue, driven by distinct distributions of cell-generated traction forces and internal stresses.",
