3D printed brain model shows potential for drug testing

I bet a 3D printed brain has much more potential than just for drug testing! How about replacing injured or diseased brain tissue and so on ...



"To address these problems, researchers in China and the US have demonstrated a 3D tissue construct that sustains a population of neuronal cells for four weeks. The team used a cell-laden bioink to print a stack of three grid-shaped layers on an array of electrodes. Spaces between and within each layer allowed nutrients to reach the cells, while the electrode array measured the cells’ electrophysiological signals."
