More about the study
Currently, the test tube brains grow to about 2mm across. The entire process involves altering the human skin cells into stem cells that are able to become any other type of cell. They are then triggered to develop into neurons. The neurons are printed in 3D form into clusters that bear a resemblance to the formation of the brain. One day, the scientists hope to be able to use the new brain tissue, find the right course of treatment for AD and related dementia, and speed up development of AD medication. If the treatment is successful, it would not be able to repeal memory loss but it could help stop further deterioration. What’s more, researchers are hopeful that the lab-grown brain parts could be of great benefit to transplantation processes.
