Scientists have taken a step toward creating human eggs from skin cells, raising hopes for future fertility treatments, though the method remains highly experimental.
In lab experiments, researchers at Oregon Health & Science University replaced the nucleus of a skin cell into an egg cell that had its nucleus removed. By triggering a process they call “mitomeiosis,” the skin cell’s extra chromosomes were reduced, producing functional eggs with the correct number of chromosomes.
Out of 82 modified eggs fertilized with sperm, only about 9 percent developed into early-stage embryos called blastocysts, and most showed abnormalities. None were grown further.
Experts say the research could eventually help women who cannot use their own eggs due to age or medical conditions, but safety concerns are significant. Scientists estimate it could take at least a decade of further research before clinical trials are even considered.
