Aston University has launched MESO-BRAIN, a major stem cell research project which it hopes will develop three-dimensional (3D) nanoprinting techniques that can be used to replicate the brain’s neural network. The project will generate adult human pluripotent stem cells that have been turned into brain cells. These will form neural networks with specific biological architectures and report on the activity of these networks in real time. The technology will mark a new era of medical and neuroscience research and could potentially be used to generate networks capable of replacing damaged areas in the brains of those suffering from Parkinson’s disease, dementia or other brain trauma. Faster, please.
