The jelly-like material present inside a eukaryotic cell - for example, plant and animal cells - that surrounds the nucleus.
A team of Japanese scientists has successfully matured mouse eggs in the laboratory, opening up the possibility of preserving the fertility of young female cancer sufferers. The research team, led by Izuho Hatada, took very early eggs from mouse fetuses and were able to mature them and use them to...
The controversial program using cytoplasmic transplantation - adding cytoplasm from the egg of a healthy donor woman to that surrounding the nucleus of an infertile woman's egg - has been further criticised this week after it was disclosed that two of the babies created had genetic abnormalities. Although it was subsequently shown...
It's strange how scientific studies become news stories. Usually, science journalists trawl the reputable journals for published papers which seem to have important or controversial findings. They write up the findings in layman's terms and get them published the following day. But the latest controversy in reproductive science has taken...
Scientists in the US have announced that babies have been born carrying the DNA of three parents: two women and a man. The babies were the result of a controversial program using ooplasmic transplantation - effectively adding cytoplasm from a donor woman's egg to that surrounding the nucleus of an infertile...
The American Association for the Advancement of Science (AAAS) has called for a moratorium on germline gene therapy - treating diseases by altering the genetic information in the egg, sperm or embryo. Changing the human genome in ways that could be passed on from one generation to the next would be...
A team of French, Spanish and Italian researchers has developed a new technique that may one day allow some infertile women to have their own genetic child. The new method, reported by the scientists in this month's issue of Human Reproduction, involves replacing the genetic information of a donor egg...
Doctors at a conference in Sydney, Australia, reported on a new and experimental technique that combines the genetic material of two women's eggs. Designed to give older women with poor quality eggs the chance to bear their own genetic children, the technique involves injecting the cytoplasm of a healthy donated...
