The researchers injected the human tissue into the rats’ somatosensory cortexes — regions that receive and process sensory information like touch or pain. After about two weeks of training, the rats began to lick a spout in search of water whenever the researchers stimulated the human neurons (they did this using blue light lasers). The researchers also used a puff of air to prod the rats’ whiskers, then observed how the human neurons responded.
After the transplants, he said, the human neurons grew to six times their original size over about eight months, making up roughly one-third of a single hemisphere in the rat brains.
The rats didn’t show signs of health issues like seizures or epilepsy, which the researchers had worried might arise. More than 70% were alive one year after the transplants.
The study is the latest example of an attempt to transplant human cells into animals. This line of scientific inquiry started decades ago, and some past tries have been successful: In 2006, developmental biologist Ali Brivanlou and a team of researchers at The Rockefeller University showed that they could grow human embryos in mouse tissue. Then in 2013, a group of Belgian researchers transplanted human neurons into newborn mice, creating functional brain circuits.
In 2018, researchers at the Salk Institute for Biological Studies implanted human brain-like structures in mice, producing results similar to the Stanford study. But they used adult mice, whereas the Stanford researchers chose newborn rats in order to see how the human neurons integrated with the rodents’ developing brain circuits.
