Summary
Scientists have used DNA from human skin cells to create "functional" eggs that can produce early human embryos, but more research is needed before these eggs can be used practically. The study represents early-stage research and highlights the potential for helping with infertility issues. The researchers note several limitations, including that the eggs currently develop abnormally and are not yet viable for creating pregnancies.
Key Facts
- Scientists turned DNA from skin cells into eggs that can make early human embryos.
- The study suggests this could help with infertility and enable same-sex couples to have genetically related children.
- The eggs had chromosomal issues, and only a small percentage developed properly.
- Researchers used a technique similar to what was used in cloning Dolly the sheep.
- The process involves combining cloning and fertilization by placing skin cell DNA into an egg.
- Experts say this work could change how we understand and treat infertility and miscarriages.
- More research is needed, with expectations of at least ten more years before potential clinical trials.
- The study was published in Nature Communications and emphasizes safety and efficacy concerns before practical use.
