The author of a study on amniotic stem cells urged Congress on Tuesday not to consider his work a substitute for the search for disease-fighting material from embryonic stem cells.
“Some may be interpreting my research as a substitute for the need to pursue other forms of regenerative medicine therapies, such as those involving embryonic stem cells. I disagree with that assertion,” wrote Anthony Atala of Wake Forest University, the author of a study published this week and widely seized upon by opponents of embryonic stem cell research as a more moral option.

I suppose a lot of scientists believe that the federal government should give their colleagues as much funding with as few strings as possible.
