EMBRYONIC stem stells are not a panacia. There is that parkenson's study which was cut short because the stem cells made the condition WORSE. You don't hear much about that one.
I think it matters to say only EMBRYONIC stem cells. This does not adress stem cells from umbilical cords or bone marrow or stomachs. THAT research is continuing. We should give MORE PR to those federally funded stem cell research which has been UNINTERUPTED.
NO ONE skewers the left like Ann........priceless.:)
You REALLY need to read the link on post #43.
Nancy, God bless her, is not right on this issue.
She won't bring this up before Nov 2.
Let Kerry bring it up, and let him also bring up his pro-infanticide views. I would very much welcome that.
So why not clone the persons OWN stem cells? It seems the need for stem cells is not an emergency room factor.
Thank you for your suggestion. I would not have seen this article without the title change.
I am thinking of a certain someone with an ovresized Bible, and a pious look upon thier face...
Similarities and differences between embryonic and adult stem cells
Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. Of course, adult and embryonic stem cells differ in the number and type of differentiated cells types they can become. Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are generally limited to differentiating into different cell types of their tissue of origin. However, some evidence suggests that adult stem cell plasticity may exist, increasing the number of cell types a given adult stem cell can become.
Large numbers of embryonic stem cells can be relatively easily grown in culture, while adult stem cells are rare in mature tissues and methods for expanding their numbers in cell culture have not yet been worked out. This is an important distinction, as large numbers of cells are needed for stem cell replacement therapies.
A potential advantage of using stem cells from an adult is that the patient's own cells could be expanded in culture and then reintroduced into the patient. The use of the patient's own adult stem cells would mean that the cells would not be rejected by the immune system. This represents a significant advantage as immune rejection is a difficult problem that can only be circumvented with immunosuppressive drugs.
Embryonic stem cells from a donor introduced into a patient could cause transplant rejection. However, whether the recipient would reject donor embryonic stem cells has not been determined in human experiments.
The unique potential contribution of human embryonic stem cells to therapies is a product of both their longevity and their capacity to produce a wide range of specialised cells in the laboratory. By contrast, adult stem cells that are grown in the laboratory appear to have much shorter lifespans than embryonic stem cells. This reduces their capacity to form new cell types. Stem cells can also be obtained from aborted fetuses and umbilical cord blood, but it is not clear whether the full range of cell types that are required for treatments could eventually be generated from these sources alone.

Stem cell research around the world
Nine of the 15 European Union nations have banned stem cell research on embryos.

Thanks, but isn't it disheartening to see how many of the Sheeple eat this stuff up? Dan Rather has orgasms over it.
Hell, I'd support that too, if I got to pick which humans we harvested ;-)
Thanks for the pics. Thankfully, someone followed the rules. Amazing how some pople have no respect for bylaws, or tradition. We can only hope your good example will promote positive changes in posting behaviors.

Well she does have an Adam's Apple. lol
