Base editing improves embryo CRISPR safety, but not enough
Improved CRISPR base editing appears to reduce unwanted mutations in human embryos, but a major barrier still prevents any near-term case for clinical use.
Key Takeaways
- Base editing reduces the unwanted mutations associated with older CRISPR approaches.
- Editing embryos requires near-perfect success because every cell descends from the embryo.
