What the hell does that have to do with bloated gas bag limbaugh slandering MJF? There is a distinct difference between adult stem cells and embryonic, you have to be just a simpleton, partisan hack to claim that dems don't know that.
Have a swell goosestepping day.
You are either naive, ignorant, or both.
My point is that MJF and company are advocating embryonic stem cell research, which has provided no results. Adult stem cells have, and continue to, and are a far more viable (and morally correct-IMHO) resource.
And perhaps the most telling is that MJF has an ad for Ben Cardin who actually voted against stem cell research. Now who is playing the sheeple for fools?
Do you know WHY he's advocating embryonic stem cells over adult? Do you? I've done some reading, and I am by no means even a student of either adult or embryonic, but it seems that embryonic stem cells have advantages and disadvantages for therapy.
Advantages: They are
Flexible: They have the potential to make any body cell.
Immortal: One cell line can potentially supply endless amounts of cells with carefully defined characteristics.
Easily available: human embryos can be obtained from fertility clinics.
Disadvantages: They could be
Difficult to control: The method for inducing the cell type needed to treat a particular disease must be defined and optimized .
At odds with a patient's immune system: It is possible that transplanted cells would differ in their immune profile from that of the recipient and so would be rejected.
Adult stem cells:
Advantages: They are
Already somewhat specialized: Inducement may be simpler.
Immune hardy: Recipients who receive the products of their own stem cells will not experience immune rejection.
Flexible: Adult stem cells may be used to form other tissue types.
Mixed degree of availability: Some adult stem cells are easy to harvest and others, such as neural (brain) stem cells, can be dangerous to the donor.
Disadvantages: They could be
Minimal quantity: They are difficult to obtain in large quantities.
Finite: They don't live as long in a culture as embryonic stem cells.
Genetically unsuitable: The harvested stem cells may carry genetic mutations for disease or become defective during experimentation.

Also, it seems that most of the treatment done to Parkinson's was done with embryonic stem cells, I wonder why the doctors would choose those over the adult? I don't know, but the researchers/doctors must have a specific reason. And before you get your panties in a wad AGAIN, I said most, not all, most.
And if you want to revert to name calling, I can hop along with you billy, why in the hell would you defend limbaugh, unless of course you're just a pandering, knee-pad wearing, gop shill with no spine and no soul. In other words an ass.
