Cercetătorii au creat 'mini-creiere' de mărimea unui bob de orez pentru studierea sclerozei multiple

Researchers from Australia and New Zealand have created 3D 'mini-brains' in the lab to advance treatments for multiple sclerosis (MS). These models, made from reprogrammed adult stem cells, mimic the human central nervous system and are the size of a grain of rice. They provide detailed insights into the destruction and regeneration of myelin, allowing real-time observation of drug effects on human cells. Myelin protects nerve fibers and facilitates rapid signal transmission in the body. Current MS treatments only manage symptoms and slow disease progression, with no therapies available to repair damage. The new model enables researchers to study immune cell-induced damage and myelin repair processes, offering a platform for testing protective or restorative drugs.
