“The biggest challenge is how this egg cut out half of chromosome – and the correct half,” Amato says. “We’re not there yet.” The team called his “mitomeiosisis” technique and tries to better understand how chromosomes like to pair and stand separate to find the way they experimentally state those conditions.
The ability of eggs and sperm in the laboratory in vitro gametogenesis, or IVG was an increasing area of research in recent years.
In 2016, a group of Japanese researchers led by the Katsuhiko Hayashi cell researcher reported that they produced healthy thought puppies after they completely made mice eggs in the Laboratory container. They later created mouse eggs using cells from men and as a result, they created a puppet with two dads. These advances are achieved by reprogramming the skin cells from adult mice into stem cells, and then further complained to develop into eggs and sperm.
Mitinori Saitou at the University of Kyoto was first documented in 2018. As his team turned human blood cells into the stem cells, which then turned into human eggs, but they were too immature to be fertilized for embryos.

But the odds raises significant ethical questions about how technology should be used. In the editor for 2017. Bioethics warned that IVG “can raise the spectrum of the ’embryo agriculture’ on a scale that is currently undergoing.” Conquested, it could allow anyone at any age to have a child. And in combination with advances in the embryo projection, the fertility clinic could use IVG to make the mass numbers of embryos and then choose those with the most desirable properties. Gene editing can also be used with IVG to capture DNA that causes a disease or create new features.
Amato says that another decade of research will probably take before IVG can consider certainly safe or efficient to test in humans. Even then, it is unclear whether the technique would be allowed in the USA, because the congress rider prohibits food and drug administration to reflect on clinical trials involving genetic manipulation of the embryo to create a baby.
“Their method is very sophisticated and well organized,” says Hayashi, now a professor at Osaka University, says About the Oregon Group approach. However, due to the high rates of chromosomal errors, “it is too inefficient and a great risk of reporting immediately to the clinical application.”
Also, because their process requires donor eggs, it could limit its use as the treatment of infertility. As IVF becomes more popular, demand for donor eggs increases and using them can include waiting time.
Amander Clark, biologist of reproductive scientists and stem cells on UCLA which was not involved in work, agrees that in its current form, mitomeiosis is not ready to use for fertility care. But in the meantime, the research has other uses.
“Mitžizes technology is an important technical innovation and could be very valuable for their understanding of Meiosis in human eggs. There is a critical area of research in human beings,” Clark says.
