Oocytes

The team from the US and Japan then transferred this gene, along with the one for GFP, into feline eggs - known as oocytes. ❋ Unknown (2011)

It is presently accepted in scientific circles that the production of eggs, known as oocytes, stops before birth for most species of mammals, including humans. ❋ Unknown (2009)

The new policy is expected to increase the availability of eggs, known as oocytes, for study and allow scientists to pursue new avenues of research, said Dr. David Hohn, vice chairman of the board's ethics and funding committees. ❋ Unknown (2009)

Experts know that the females of most species of mammals, including humans, stop producing eggs, known as oocytes, soon before birth, and that the number of eggs they are born with is the number they will have for the rest of their lives. ❋ Unknown (2009)

Specialists at McGill University in Montreal have developed a protocol in which they retrieve immature eggs (i.e. "oocytes") from a woman's ovaries, induce the oocytes to mature in a lab dish, then deep-freeze them; the oocytes can then be thawed for fertilisation at a future point.

No abnormalities were detected in oocytes from calorie-restricted mice. ❋ Ann Lukits (2011)

"Without Edwards there would be no market for oocytes (unfertilized eggs); without Edwards there would be no freezers full of embryos waiting to be transplanted into uteruses or, more likely, to be used for research or else die abandoned and forgotten by all," Carrasco said. ❋ Clay Chiles (2010)

The technique is called gamete-targeted lentiviral transgenesis — essentially, inserting genes into feline oocytes eggs before sperm fertilization. ❋ Unknown (2011)

He was also the first to show that in-vitro fertilised human oocytes could give rise to early-stage embryos and blastocysts. ❋ Alok Jha (2010)

Spindle abnormalities, which can lead to chromosomal errors, also increased in control oocytes from less than 10% at three months to almost 65% at 12 months. ❋ Ann Lukits (2011)

Maternal diet-induced obesity alters mitochondrial activity and redox status in mouse oocytes and zygotes. ❋ Unknown (2010)

The number of healthy unfertilized oocytes, or eggs, was significantly lower in control mice than calorie-restricted mice, the study found. ❋ Ann Lukits (2011)

Using an established mouse model of maternal diet-induced obesity and live cell dynamic fluorescence imaging techniques, the researchers demonstrated that maternal obesity prior to conception is associated with altered mitochondria in mouse oocytes (eggs) and zygotes. ❋ Unknown (2010)
