Japan team offers fertility hope with stem cell eggs

By raymumme

Japanese stem cell scientists raised hopes of a cure for infertility in humans Friday when they announced they had created viable eggs using normal cells from adult mice.

The breakthrough raises the possibility that women who are unable to produce eggs naturally could have them created in a test tube from their own cells and then implanted in their body.

A team at Kyoto University harvested stem cells from mice and altered a number of genes to create cells very similar to the primordial germ cells that generate sperm in men and oocytes -- or eggs -- in women.

They then nurtured these with cells that would become ovaries and transplanted the mixture into living mice, where the cells matured into fully-grown oocytes.

They extracted the matured oocytes, fertilised them in vitro -- in a test tube -- and implanted them into surrogate mother mice.

The resulting mice pups were born healthy and were even able to reproduce once they matured.

Researchers said the findings, published in the US journal Science, provided a promising basis for hope in reproductive medicine.

"This achievement is expected to help us understand further the egg-producing mechanism and contribute to clarifying the causes of infertility," professor Michinori Saito told reporters ahead of publication.

"We intend to continue this research with monkeys and humans," he said.

But Saito cautioned that this was not a ready-made cure for people with fertility problems, adding that a lot of work remained.
