CRISPR Breakthrough: Scientists Correct Down Syndrome Chromosomes in Lab

In a landmark study from Cell Reports, researchers used CRISPR gene editing to silence the extra chromosome 21 in Down syndrome cell models. The treatment:

🧬 Restored normal cell division
⚡ Improved neural function by 47%
🛑 Caused no detectable DNA damage

“This isn’t a cure—it’s a proof of concept for future therapies,” cautions lead scientist Dr. Maria Castro. While human trials are years away, the technique may also help treat other trisomy conditions.
