Whether they’re in the brain or intestines, many tissues are programmed to bend, twist, and fold in specific ways. Now, scientists have harnessed this programming to create bowls, coils, and ripples out of living tissues that fold themselves up. To do so, the researchers started with plugs of cells taken from a connective tissue in mouse embryos. Called the mesenchyme, this tissue contains cell layers that either stretch or pinch together. When a pinching layer sits above a stretching layer, the two together cause the tissue to bend inward like a bow. Using a 3D printer, the researchers...
