When cells grow together, they often align with their neighbors, forming liquid crystal-like patterns known as “nematic order.” But that order isn’t perfect, and at certain points, the alignment can break down, creating “topological defects”: small regions where cells swirl or fan out instead of lining up cleanly.
And according to research published in Science, what looks like a defect can be used strategically as built-in instructions for shaping larger structures. Instead of growing upward, cells can store and release stress in certain places along a previously flat sheetlike structure, forming a bowl, a ridge, or a fold.
