New study warns of dangers of gene editing in human embryos

A new study highlights the limits of gene editing in human embryos. Researchers have used CRISPR-Cas9 in an attempt to correct genetic errors in human embryos. However, embryonic cells have difficulty repairing broken DNA strands, leading to further mutations. In one study, researchers fertilized donated eggs with donated sperm using intracytoplasmic sperm injection (ICSI) to […]
