First functional human brain tissue produced through 3D printing

Scientists at the University of Wisconsin-Madison are the first to develop the 3D-printed brain tissue, which grows and behaves like a natural brain tissue. The group used a new 3D-printing method, stacking layers of tissue horizontally rather than vertically and using a softer bio-ink (see 101). The model will allow scientists to better study neurological diseases, including Alzheimer's and Parkinson's.
