Nearly complete human brain grown in US lab: scientist

An almost complete version of a tiny human brain has been grown in a US lab in a move that could bring major strides to the treatment of neurological diseases, a scientist says. Rene Anand, a professor at Ohio State University, has grown in a dish a brain equal in maturity to that of a five-week-old fetus, his university reported. "It not only looks like the developing brain, its diverse cell types express nearly all genes like a brain," Anand said.
