stem cells

Cells that maintain the ability to replicate them selves as well as form other cells of the body.
Two major classificiations exist; embyronic stem cells which are totipotent or pluripotent and can make any cell of the organisms body and adult or tissue specific stem cells which are multipotent and can produce only a limited range of cell types.
Often confused by the laymen and stupid right-wing politicians as tiny little babys but really more similar to dandruff than babys.

Maybe if we said that some gay french muslims were using diabetes and parkinsons to terrorize christian evangeslists he would athorize 200 billion dollars and 2000 cell lines (or paa-tench-al persons 4 u Dubs), (though at 50 trillion cells per dead GI we should really get around 100'000 trillion stem cells)
