Excerpt:
Imagine the brain’s blood vessels as a bustling highway system, twisting, turning, and pulsing with life. Now picture a traffic jam in one of the most critical intersections: that’s what happens in cerebrovascular diseases, especially when stenosis (narrowing of blood vessels) blocks the flow.
Doctors have tools to clear the jam, like surgical rerouting, balloon angioplasty, and stents. These can help restore blood flow, but here’s the catch: they don’t rebuild the real complexity of the brain’s vascular network. It’s like fixing a highway with straight pipes when the brain needs winding mountain roads.
Traditional lab models? They’re often too simple. Static cultures and microfluidic chips can’t mimic the brain’s dynamic flow, flexible vessel walls, or biological responses. That’s like studying traffic patterns using toy cars on a flat board.
