Assembling Cells Into Artificial 3-D Microtissues, Including A Tiny Gland

Chemists have developed a way to assemble cells into 3-D microtissues and even tiny glands, much like snapping together toy building blocks to make a simple machine. Such microtissues could serve as niches for studying how cells, such as stem cells, work together. Or they could be assembled into larger structures as artificial, implantable organs.
