Researchers from the University of Wisconsin in the USA have 3D printed living tissue from the cortex and striatum of the brain. They will be used to study brain functions and various pathologies such as Parkinson’s and Alzheimer’s diseases. Scientists’ studies have been published magazine Cell Stem Cell.
Scientists used special bioink obtained from induced pluripotent stem cells to create the brain. They were dense enough to support the structure of the brain and enable printed neurons to connect with each other. Scientists also used horizontal printing technology, which is not considered traditional.
Specifically, the authors created the cerebral cortex and striatum; The latter plays an important role in the regulation of movements, as well as in planning, motivation and reward processes. The new method effectively mimics the complex communication networks of the human brain, offering scientists enormous potential to study brain function and pathology.
Previously in Russia was created fertilizer made from bird droppings that restores the “health” of the soil.
