3D micro brain models speed MS research
Tiny 3D models that mimic vital aspects of the human nervous system have been developed in a step that could accelerate drug research for neurological conditions such as multiple sclerosis (MS). The millimetre-wide models - created using stem cells from human skin samples - will be used to study myelin, an insulating substance that helps nerve cells communicate with each other. Researchers say the models are the most natural representation of human myelination developed in a lab and are a promising platform for studying neurological diseases and for testing drugs for conditions linked to myelin loss, including MS. Nerve cells are found in the brain and the spinal cord and connect to each other with branch-like links called axons, which have an insulating coat similar to electric cabling. This insulating coat is called myelin, and it aids the electrical and chemical information flow between cells.
