Scientists create viable human eggs from skin cells

October 01, 2025 由 AI 报道

Researchers at Oregon Health and Science University have successfully generated functional human egg cells from skin cells, which were then fertilized in the lab to produce early-stage embryos. This breakthrough, published in Nature, represents the first time such eggs have been matured and used for fertilization outside the body. The technique could eventually aid infertility treatments and genetic disease prevention.
