Mitinori Saitou at the University of Kyoto documented for the first time in 2018 how his team turned human blood cells into stem cellswhich they then transformed into human eggs, but were too immature to fertilize them, to produce embryos.
Startups Conception Biosciences, Ivy Natal, Gameto and Ovelle Bio are working on making eggs or semen in the laboratory.
But the perspective raises significant ethical questions about how to exploit technology. IN Editors 2017Bioethics warned that IVG “can raise the specter of” embryos breeding “on a scale now unimaginated.” This can be allowed to have a child at any age. In combination with progress in screening of the embryos of the Fertility Clinic in the future, they could exploit IVG to create mass numbers of embryos, and then choose those with the most desirable features. Editing genes can also be used from IVG. causing the disease or creating novel features.
Amato claims that this will probably take another decade of research before IVG is considered safe and sound or effective enough to test them in humans. Even then it is not clear whether the technique would be allowed in the United States, because the Congress player prohibits the administration of food and medicines to consider clinical trials, which include genetic manipulation of the embryo to create a child.
“Their method is very sophisticated and well organized,” says Hayashi, currently a professor at the University of Osaka, about the approach of the Oregon group. However, due to the high indicator of chromosomal errors, “it is too ineffective and high risk to immediately follow clinical use.”
In addition, because their process requires a donor eggs, it can limit its exploit as infertility treatment. As IVF becomes more popular, the demand for donor’s eggs increases, and their exploit may include waiting time.
Amander Clark, a reproductive scientist and a biologist of stem cells in UCLA, who was not involved in work, agrees that in its current form the mythometiosis is not ready for exploit for fertility care. But in the meantime, other applications have.
“Mytomeiosis technology is an important technical innovation and can be highly valuable for our understanding of mejosis biology in human eggs. Mejotic errors grow as women aged. Therefore, understanding the causes of mejotic errors is a critical area of research,” says Clark.
