Bone marrow may restore cells lost in vision diseases

Title is incorrect and false.

Title is incorrect and false.

So this is an cure/therapy with embryonic stem cells?
If so, wow!

[Vinny]

how do you know?

Well, the PC crowd will now demand that the song "Three Blind Mice" be banned.

To get human retinal cells at the same stage of development, however, would involve taking stem cells from a foetus during the second trimester of pregnancy.

But Dr Robert MacLaren, a specialist at Moorfields Eye Hospital who worked on the research, said they did not want to go down that route.

He said the aim now would be to look at adult stem cells to see if they could be genetically altered to behave like the mouse retinal cells.

There are some cells on the margin of adult retinas that have been identified as having stem cell-like properties, which the team says could be suitable.

Dr MacLaren stressed it would be some time before patients could benefit from such a treatment, but he said that at least it was now a possibility.

Experiment with embryonic stem cells injected into Micheal J. Fox.

This doesn't promote the cause of destroying unborn children! We can't have this!!!!!!!!!!!!!!!!!!

Scientists say they've restored the vision of blind mice

Dare I suggest that in the study, n=3?

[VOA]

"...The finding also gets around the thorny ethical question of
using embryonic stem cells. In fact, MacLaren said, "we do
not want embryonic stem cells because they are too undifferentiated."

Shoot, those ethical questions went out the window here in Missouri
when we were effectively told that we'd kill Michael J. Fox if
we didn't vote for Amendment 2.

The writer of this article is behind the times.

The real issue is what we are going to do about adult individuals who have demonstrated that they have superior stem cells for some purpose.

Millions of lives may be saved or extended if we can just sacrifice the holders of those superior stem cells.

Michael J. Fox might stop jerking around and Rush Limbaugh might hear without equipment.

Nancy Pelosi could grow a new face, which she sorely needs.

Obviously we have some laws to change first.

[gaijin]

What exactly do you think is misleading? Be more specific.

[gaijin]

we are transplanting cells at the exact time that they are destined to become photoreceptors -- i.e., they are past the point of no return,"

Seems the cells he's using are LINEAGE cells --they are no longer totipotent (are not embryonic) and have committed to a specific lineage.

In fact, it seems to me he's SPECIFICALLY saying that earlier efforts using ES cells were problematic and that that's why they're NOT doing that, this time 'round.

Feedback?

Oh, OK. Yeah, I'd be cool with that. I mean, when people hear, "adult stem cells" they just hear the "stem" part only and freak out, so....I'd be cool with "cell transplants".

In fact, they should have used that terminology from the beginning, to avoid ethnical sensibilities/public ignorance.
