Scientists at the University of Wisconsin-Madison have developed the first 3D-printed brain tissue that can function like regular brain tissue.“We think this work could help people to understand neuropsychiatric diseases, like Alzheimer’s or Parkinson's, compared to the other models,” said Yuanwei Yan, a scientist in the Zhang Lab at the University of Wisconsin-Madison.This is how it works: The researchers horizontally situated brain cells in a “bio-ink” gel.
“Our cells are a lot better compared to an organoid. They mature a lot faster and the function is way better,” Yan said. Brain organoids, which are structures derived from stem cells, are used to study brains. Now with 3D printing, this method allows scientists to have more flexibility in their studies. And it uses materials and machines available in many labs. The 3D-printed brain tissue can be used to study things like watching the brain grow, testing new drug candidates, and watching interactions between health tissue and tissue affected by Alzheimer’s.
When asked about any concerns he wanted to address, Yan said this new development will not be used to create a full brain.
