"Breakthrough: 3D-Printed Neural Tissue Functions Like Human Brain"

Scientists at the University of Wisconsin-Madison have achieved a world-first breakthrough by successfully 3D-printing human brain tissue that can grow and function like real brain tissue. This innovation has the potential to revolutionize neuroscience research and aid in understanding and treating neurological and psychiatric disorders. The new 3D printing method involves growing brain cells from induced pluripotent stem cells and laying them out horizontally within a soft gel "bio-ink," allowing the neurons to form networks and communicate with each other. The study, published in Cell Stem Cell, opens up new possibilities for studying the brain's complex network of cells and connections.
