🧬 Big Breakthrough in Genetics! Scientists in Japan have used CRISPR-Cas9 to remove the extra chromosome that causes Down syndrome (Trisomy 21) in lab-grown human cells! 📍 This research from Mie University showed that once the extra chromosome was removed: ✅ Cells started working normally ✅ Gene activity balanced out ✅ Cell growth improved 💡 While it’s still in the lab stage (not a treatment yet), it’s a major step toward understanding and possibly treating genetic disorders in the future.
