Lab-grown brain-spinal cord model suggests potential reversal of permanent nerve damage

Summary

This article discusses a scientific breakthrough where researchers developed a lab-grown brain-spinal cord model (assembloid) to study nerve damage and regeneration. It explains how neurons and axons function, and how damage to the central nervous system typically results in permanent disability due to the loss of axon growth ability. The research suggests that this 'irreversible' nerve damage may potentially be reversed, offering hope for treating spinal cord injuries and neurodegenerative conditions.
