Scientists in Oregon have created fertilizable eggs from human skin cells, marking a significant step in reproductive research, though the eggs currently have chromosome abnormalities that need further refinement before potential human trials, which could take a decade.
Scientists have successfully produced functional human eggs from skin cells in the lab, which can be fertilized to form early-stage embryos, potentially offering new fertility treatments, though significant technical and ethical challenges remain.
Researchers at Harvard's Wyss Institute have developed a method to induce human induced pluripotent stem cells to initiate meiosis outside the body, a key step toward creating healthy eggs and sperm in vitro, which could help address infertility issues.
