I'm pretty sure they are called gametes. Gametes are the female and male reproductive cells in meiosis which have half the number of chromosomes than the old cell Hope this'll help ya out!
Embryonic stem cells refer to pluripotent cells that are generally derived from the inner cell mass of blastocysts (day 5). Stem cells have been derived from gonadal ridges and mesenteries (3200 to 4000) extracted from aborted five-to-nine week old human embryos.
60,000,000 cells die each second. 3,600,000,000 cells die die each hour.
An old cell splits in two, and then there are two cells - half the old one and the other half of the old one, both of which are 'new' individual cells.
cancer cell are cells that have a problem in their DNA which can lead to out of control division and old cells have no problems with their DNA they just die and cause no damage

A stale cigarette. A stale cigarette has no taste whatsoever.
It is more difficult to break a bundle of sticks.The old man carried the bundle on his bent back.
The answer is to let a 13 year old back in school
Every day oxides (often due to free radicals) gum up the works in your cells ... eventually the cells die. some are replaces by "scar tissue" and some are just not replaced. The cumulative effect is called aging.
Cells dont get old
you can do that in your local gamestop
Your blood cells are manufactured in the center part of your bones called the marrow. Have you ever broken a chicken bone? The center is called the marrow. Your liver is what recycles the old cells cleaning the blood.
for a 6 week old mouse there are about 80-100x10^6 splenocytes (whits blood cells).

Implantation of the 5-day old embryonic stage of cells, called the blastocyst occurs. The blastocyst eventually gives rise to gastrula, and further development of the fetus proceeds.
