was not involved in the research. "That these cells were able to integrate into tissue in an animal model and actually survive - it was extremely important to show that. Now the question is what will these cells do in a human brain? Will they be able to survive for the long term and rebuild circuitry? This work is a first step toward that end."

In addition to using the cells in treatments to repair or replace damaged brain tissue, the ability to massively expand cell populations could prove useful in efforts to test the safety and efficacy of new drugs. It is also possible to genetically modify the cells to produce neurotrophins - substances that help brain tissue survive, researchers said.
