Tech: 3D printing set to get a good head start

Researchers from the Columbia University Irving Medical Center are making headway in their work to treat human baldness, thanks to 3D printing. The team, led by Angela Christiano, has found a way to grow human hair in a dish using stem cells and 3D printed plastic molds that mimic the natural microenvironment of hair follicles. For the first time, scientists have successfully generated human hair follicles in a dish without the need for skin implantation. This achievement is owed in part to 3D printing technologies, which enabled the research team to closely recreate the 3D environment in which human hair cells live.
