Researchers have successfully identified over 5,000 proteins that are present in embryonic stem cells, tripling the size of previous results and in the process creating the largest quantified protein map to date.
Stem cells hold great potential in biology and medicine, but a host of questions lingers about how they operate and convert into other cells. To help answer these questions, researchers have begun taking a 'big picture' approach, identifying all the proteins that are expressed in stem cells.
Currently, around 1700 proteins have been identified in stem cells. Now, using mass spectrometry and special "heavy" amino acids (made with carbon-13), Matthias Mann and colleagues quantified 5111 distinct mouse stem cell proteins. As expected, a good portion of these proteins are involved in rapid cell growth, but overall the proteome encompassed a broad range of cell functions.
While this study may help uncover new clues to stem cell biology, it does raise the bar on the complexity of these important cells, considering they express at least 25% of all known mouse proteins.

They are working with mice.
Would you turn down a cure derived from these methods? For your children?
Would you toss one of your babies into a blazing furnace if you believed it would somehow cure sick children you may have?
Guys, lighten up!
Embryonic stem cells are sooooo yesterday! Ever since they figured out how to make an adult stem cell into one of the undifferentiated kind, the whole embryonic stem cell issue lost its luster. Now there are better, more varied and less political stem cells.
The issue is gone.

No. Mice babies sure. Monkey babies also ok.
No reply? FYI I’d toss myself in if it would make a difference for my children. Medicinal advances by animal sacrifice have led to many of the wonders on the modern age. I’m still not getting what this has to do with my hypothetical children. I’m just gonna write it off as you shooting off the post without reading the article and just assuming embryo = bad evil godless doctors.
The research is being done on a higher mammal model. If successful, from whence will come the embryonic stem cells to do this in humans? ... Your feign confusion is such an old liberal ploy. You are advocating for the destruction of human embryos in oorder to obtain the cures, hypothetical cures. 'Would you turn down a cure derived from these methods' is the classic liberal puke ploy, since the 'cure' would be depending upon dissecting human embryos for the stem cells in such a cure, unless the technology in the higher model yileds a method for deriving stem cells that doesn't kill the embryo, which is not what this study was searching over.
Brush away the killing of embryonic humans because of the greatness of the cure for the older humans, is the ploy you made. Now that is your cue to try and dissemble further, in typical liberal style. But I won't be responding further to your drivel.
My mistake.
Seems I should read the whole article.
However, McAmnesty and his support of Human Embryonic Stem Cell research is what this is all about.
This has nothing to do with McRINO. They are trying to get a handle on the molecular biology of development. If you want veterans and other people who suffer with amputations to be able to regrow limbs like salamanders, then this topic must be mastered. I haven't read anywhere yet that it must and can only be done with human embryonic stem cells.
Firstly it’s not YOUR God. There is only one God, and we belong to him. Secondly your telling me you wouldn’t take mice embryo research and apply it to your own family? You must really love animals maybe you should go join PETA?
Humans and Mice share many traits in the protein structure of numerous things. If we can see patterns using mice embryos it aids a whole host of research many of them unrelated to human embryo research. Next time read the article instead of just seeing embryo and assuming bad things.
Sorry buddy, but he is my God, however, I think this is just a matter of semantics on your part.
Try reading the whole thread, I already acknowledged my mistake.
