Researchers use stem cells to grow 3-D lung-in-a-dish.

By coating tiny gel beads with lung-derived stem cells and then allowing them to self-assemble into the shapes of the air sacs found in human lungs, researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have succeeded in creating three-dimensional lung “organoids.” The laboratory-grown lung-like tissue can be used to study diseases including idiopathic pulmonary fibrosis, which has traditionally been difficult to study using conventional methods.

/…/ Gomperts and her colleagues started with stem cells created using cells from adult lungs. They used those cells to coat sticky hydrogel beads, and then they partitioned these beads into small wells, each only 7 millimeters across. Inside each well, the lung cells grew around the beads, which linked them and formed an evenly distributed three-dimensional pattern. To show that these tiny organoids mimicked the structure of actual lungs, the researchers compared the lab-grown tissues with real sections of human lung.
