"Breakthrough: 3D-Printed Brain Tissue Functions Like Real Human Brain"

Scientists have successfully 3D-printed functional human brain tissue less than 0.01 inch thick, containing nerve cells and glia that can communicate and form networks. This breakthrough could complement other brain models and aid in testing new drug candidates for brain-related disorders. The printing technique allows for more control over cell placement and faster network formation compared to organoids. However, challenges such as gel softness and nutrient demands still need to be addressed for further refinement of the technology.
