Living robots made from human cells may induce neuron healing

Biological robots made of human tracheal cells can promote the repair of wounded neural tissue in the lab. While the research is still in an early stage, the findings suggest that the robots could one day treat the cellular damage that can occur after a stroke or with paralysis. In 2020, Michael Levin at Tufts University in Massachusetts and his colleagues created living robots out of frog cells, called xenobots.
