29 3 Full Breakdown

Summary

Story summary

Northwestern University researchers grew human spinal cord organoids to model spinal cord injury.
After simulating injuries, they applied IKVAV-PA therapy, which reduced inflammation and scarring versus untreated samples.
The therapy increased nerve cell regrowth in the organoids relative to controls.
The organoids mirrored real injury responses, supporting a model for future human testing.
Nature Biomedical Engineering published the findings.
