Researchers Create Functional 3D-Printed Brain Tissue for Neurological Studies

Researchers at the University of Wisconsin-Madison have developed the first functional 3D-printed brain tissue that mimics typical brain functions. Using a horizontal 3D printing approach with induced pluripotent stem cells and a softer bio-ink gel, the printed tissue allows neurons to grow and communicate like natural brain tissue.

The method enables precise control over cell types and arrangement, fostering connections similar to those observed in human brains. This innovative model could revolutionize the study of neurological disorders, such as Alzheimer’s and Parkinson’s disease, offering insights into brain function and communication.
