wait a minute. ESC research is 'aimed at treating:' but ASC research has already been used to treat 9 diseases? Seems to me you would want to put your [and my, tax] money where it would do the most good.
My understanding is that ASC research is examining the same areas as ESC research [ healing spinal damage, for example], and it's more successful.
And I guess I don't understand how ESC research can replicate diseased cells. How does that happen unless the E. stems cells themselves are diseased?
the article at the url above is talking about "..somatic cell nuclear transfer to generate stem cells that are customized to the specific patients.. "
Couldn't this be done much more easily just by taking ASC from the patient?
"We hope to correct the genetic defects in these patient-specific cells, direct their differentiation into blood, and transplant kids with these genetically matched autologous cells. "
Is it easier to correct the genetic defects in ESC even after the extra step of somatic cell nuclear transfer?
I don't get it. If you can correct the defects in ESC, why can't you correct them in ASC, skipping the extra steps?
"Although it is true that no one has to date been treated with cellular therapies based on human embryonic stem cells,..."
and
"As for the criticism that no one has been cured with embryonic stem cells, the field of human embryonic stem cell research is a mere 7 years old, ..."
How old is field of ASC? Isn't it about the same age?
the article laments, "and the adult blood stem cells from Fanconi's patients cannot be maintained in culture."
Wouldn't the research dollars be better spent on trying to correct the problem of maintaining ASC in a culture?
An article I read today said that it will likely be ten or more years before anyone is being successfully treated with embryonic stem cells.
I dunno, it looks to me that some people just want to study Embryonic stem cells come hell or high water , without any regard for effectiveness or cost.
Course it's always easy to spend other people's money than your own, so I can't blame these researcher for trying to get tax money.
But:
If they really really believe that ESC research is going to pay off better than ASC research, why don't they spend their own money?
I don't have a problem with them making a buck on it if/after it pays off.
