3D Printed Brain With Working Neurons Grown In Wisconsin

Researchers from the University of Wisconsin-Madison reported the creation of a functional 3D printed brain. They used human pluripotent stem cells (hPSCs) as their base material, creating a layered structure with their bioink gel.

The paper, which was published in Cell Stem Cell, claims that functional neural circuits were created in two to five weeks after printing. They also claim their platform can create almost any type of neuron, giving it an advantage over current  mini-brain models.

The researchers hope that their work can someday be used to model and study diseases like Alzheimer's, and potentially be used for drug testing.
