Researchers have manufactured eggs that allow infertile women to give birth to children. They have made mammalian eggs that can be fertilized to produce a healthy child. For the first time, the eggs have been made from scratch without the too help from of an animal.

Though the research was conducted on mice and only eggs, it makes a hope for the future of infertility females. "Developing similar culture systems in other species should be a matter of technicality", said Dr. Dusko Ilic, readers of stem cells science, King's college London.

The Japanese team, who experimented the research for the first time- led by Professor Katsuhiko Hayashi, from Kyushu University - obtained stem cells from mice embryos and mature cells were taken from the tips of mice tails and create induced pluripotent stem(iPS) cells. A mixture of stem cells and gonadal cells were taken from 12-day old mice embryos. That played a key role in egg formation, The Wall Street Journal reported.

The scientists then fertilized some of the eggs by using mouse sperm. The fertilized eggs were then implanted into the Uterus of albino female mice. Out of 1,348 embryos eights, pups were born.

"This approach might be useful for conventional infertility treatments as well as the female who have lost their infertility," said Professor Richard Anderson, from the University of Edinburgh.

The scientists published an article in Nature said," The culture system will provide a platform for elucidating the molecular mechanisms underlying low potency and the production of oocytes of other mammalian species in culture"

According to Tech Times, If the research will work out, it can be used to produce eggs for infertile women or those who have a lower number of eggs to enable them to have IVF. This research may also be used to produce egg cells from male skin cells, which makes two genetic fathers.

Before the use of this technique, still many practical and ethical challenges to be resolved.
