Nanowire mats mimic brain tissue to reveal astrocytes in natural form for the first time

SMRTR summary

Scientists created nanowire mats that replicate brain tissue texture, allowing astrocytes—the brain's most abundant support cells—to grow in their natural star-like shape for the first time in laboratory settings. This breakthrough enables real-time observation of these critical cells that maintain brain function, potentially advancing research into Alzheimer's, Parkinson's, and other neurodegenerative diseases.
