Uppsala University Jun 18 2025 With the aid of a 3D printer, researchers at Uppsala University have succeeded in creating a model that resembles human nerve tissue. The model, which can be cultured from the patient's own cells, makes it possible to test new drug treatments in a lab environment. Motor neurons are nerve cells that control our muscles by sending signals from the brain and spinal cord out to the body. In diseases such as Amyotrophic Lateral Sclerosis (ALS), these cells are
