Stem cells capable of differentiating to multiple lineages may be valuable for therapy. We report the isolation of human and rodent amniotic fluidderived stem (AFS) cells that express embryonic and adult stem cell markers. Undifferentiated AFS cells expand extensively without feeders, double in 36 h and are not tumorigenic. Lines maintained for over 250 population doublings retained long telomeres and a normal karyotype. AFS cells are broadly multipotent. Clonal human lines verified by retroviral marking were induced to differentiate into cell types representing each embryonic germ layer, including cells of adipogenic, osteogenic, myogenic, endothelial, neuronal and hepatic lineages. Examples of differentiated cells derived from human AFS cells and displaying specialized functions include neuronal lineage cells secreting the neurotransmitter L-glutamate or expressing G-protein-gated inwardly rectifying potassium channels, hepatic lineage cells producing urea, and osteogenic lineage cells forming tissue-engineered bone.

Report: Amniotic Fluid Yields Stem Cells
Researchers say amniotic fluid yields stem cells
Amniotic fluid a promising stem cell source
So that would be a positive. However, I don't think this new AFS cell research would satisfy the appetite out there for the use embryonic stem cells (just as adult stem cell research has not). Scientifically, there are difference between all three types of stem cells (adult, embryonic, and amniotic fluid). The AF have properties of both adult and embryonic stem cells, but are closer to embryonic.
So the main thing is not to let the media spin anything...closed down the debate...etc. So us pro-lifers still got to call our representatives and tell 'em to vote NO on HR 3!
I'm of two minds about this. I will have to educate myself.
Who paid for that study? Source affects outcome

I heard this story today. Wow -- it will surely derail the stem cell votes in Congress. At least, postpone them.
Great news! BTTT!
