Precisely engineering 3-D brain tissues

get "claustrophobic," Demirci says. "In small gels, they don't necessarily send out as long neurites as they would in a five-times-larger gel."

In the long term, the researchers hope to gain a better understanding of how to design tissue implants that could be used to replace damaged tissue in patients. Much research has been done in this area, but it has been difficult to figure out whether the new tissues are correctly wiring up with existing tissue and exchanging the right kinds of information.

Another long-term goal is using the tissues for personalized medicine. One day, doctors may be able to take cells from a patient with a neurological disorder and transform them into induced pluripotent stem cells, then induce these constructs to grow into neurons in a lab dish. By exposing these tissues to many possible drugs, "you might be able to figure out if a drug would benefit that person without having to spend years giving them lots of different drugs," Boyden says.
