Although the researchers began with an egg cell, they do not believe it is required to start the same development.
Other things, such as smoking cigarettes and certain types of chemotherapy,can accelerate egg cell death and promote an earlier menopause.
One of the ovaries releases an egg cell, encased in a tiny sac known as follicle, every month which begins the monthly menstrual cycle of the girl.

The female ovaries contain almost half-a-million egg cells, but only 400 or so will ever get the opportunity to create a new life.
Egg cells live for only 12- 24 hours after ovulation, which means that timing sex for immediately before or after ovulation improves the chances of conception.
The ovaries develop normally at first, but egg cells(oocytes) usually die prematurely and most ovarian tissue degenerates before birth.
The ovules are 8 in number and arranged in the form of 3+2+3(from top to bottom)i.e 2 synergids& 1 egg cell, 2 polar central cells, 3 antipodal cells. .
Research indicates that egg cells are highly susceptible to harm from free radicals, the unstable oxygen molecules that are produced as the body breaks down toxins.

Unlike normal egg cells, they can divide to form new cells, which Perry says makes them more like other cells in the body, like skin.
In a classic experiment,he replaced the immature cell nucleus in an egg cell of a frog with the nucleus from a mature intestinal cell. .
When female animals form egg cells inside their ovaries, they deposit messenger RNAs(mRNAs)-a sort of genetic instruction set- in the egg cell cytoplasm.
In this process, scientists remove the DNA(located in the nucleus of a cell) from the mammary gland of an original sheep,then transfer it into the nucleus of an egg cell.
Parthenogenesis, or the development of an embryo from an egg cell without the latter having been fertilized, has been described in species of Thalictrum, Antennaria, and Alchemilla.
The group had some success in 2012, by managing to turn mouse skin cells into primary germ cells- a kind of immature egg cell in its early stages of development.

A polar body is a smallhaploid cell that is formed concomitantly as an egg cell during oogenesis, but generally does not have the ability to be fertilized.
Typically the egg cell is not released or picked up at ovulation, but fertilized within the ovary where the pregnancy implants.[1][2][3] Such a pregnancy usually does not proceed past the first four weeks of pregnancy.[3] An untreated ovarian pregnancy causes potentially fatal intra-abdominal bleeding and thus may become a medical emergency.

Embryology- the science of building a baby from a single fertilized egg cell- had been a hot topic in the early part of the 20th century, but progress sputtered to a halt as scientists realized they lacked the technical tools and scientific framework to figure it out.
