Scientists have successfully transplanted optic stem cells into the eyes of blind mice, restoring their sight.

Cell transplants 'restore sight'

The wonders of stem cell research....

"They were able to help them see again by transplanting immature retinal stem cells into their eyes.'...

1 - Early stage retinal cells are taken from a newborn mouse
2 - They are transplanted into the retina of a mouse which has lost its sight
3 - The cells implant and connect with existing cells in the eye, restoring some sight to the mouse.
Sounds like Adult Stem Cell Research did the trick.  I didn't see anything in the article talking about using Embyros?  Did I miss it?

Michael J Fox is RIGHT! 

I hope Limbaugh is feeling good for costing the Republican party the Senate!  If he hadn't opened his mouth, Missouri would have won a REP seat! lol

But on topic again, stem cell research better do what it claims!  Hopefully this is the beginning of a trend!

I'm confused...is this Adult Stem cells or Embyronic Stem cell?

From the article:
The team took cells from three to five-day-old mice, a stage when the retina is about to be formed.
If the cells are from a three to five-day-old mouse then its 'Adult Stem Cell', right?

It's not ASCR, it's to do with differing stages of development in mice compared to humans. When mice are born their eyes are not properly developed, like dogs.

+1 And sorry MJF is wrong, Ironchef.  Embryonic is crap, compared to the accomlishments of ASCR, but there's already 2 lengthy threads about this subject. Let's go read those instead of rehashing it here.

You call making blind mice see, crap? It's much better than anything accomplished by ASCR. ASCR has it's place, but the developments it produces are not as dramatic as ESCR. The results from ASCR do tend to be more immediately practical, but they do not have such great potential.

Try reading the WHOLE article next time:

The Article wrote:

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.
Adult stem cells are the future, I don't know why you guys are clinging to the past.

Number of treatments from Adult stem cells: 156.
Number of treatments from embryonic stem cells: 0

Nevertheless, they have successfully treated the mice with embryonic stem cells. Adult stem cells were not used. Your quote is just pointing out that they would rather use adult stem cells in future. There is no guarantee that will work though.

*edit*
I was kind of hoping this thread wouldn't just turn into another ASCR vs ESCR flame war. If you ask me both are important branches of research. ASCR for the short term ESCR for the long term.

Are we reading the same article...PLEASE someone explain to me where in the article is shows that it was embryoics stem cells?  The cells were from three to five-day-old mice, which means to me that its 'Adult Stem Cells'. 

Someone correct me if I'm wrong.

I have already been over this. It is to do with the differences in stages of development between mice and humans. When a human is born their eyes are already developed and work. Mice, like dogs, are born blind - their eyes develop later. In the article it says the stages of development of the cells used is equivalent to embryonic stem cells in humans.

Yay, they're still mouse cells, not human cells.  As AlbertWesker[RE] pointed out, zippo treatments from human embroynic cells.

So? As I have continually said, ES research is all about the potential for the cells. It is research for the long term, which is why there is so little interest in private funding for it. ASCR is a much more practical research area for the near future, with many practical treatments already underway.

Another recent development in ESCR is the development of hybrid Cow ES cells. Cow eggs are combined with human DNA to produce cells that can be grown without the need for human foetuses to be involved (unlike Lanza's idea, this actually works). This practice has also been condemned by religious groups. A lot like vaccination was, it was thought (by religious types at least) that using the strain of smallpox from cows as a vaccine would cause a person to exhibit bestial tendancies. It did not, obviously, and vaccines now save millions of lives.

Anyway, another BIG reason treatments based on ASCR are available is that ASCR has been around for much longer. More than 50 years of ASCR compared to 8 years of limited ESCR. No wonder there are no ESC treatments yet.

Moooooo.

Have you noticed the utters on some of cows, errr chicks (got my animals mixed up), in these guys sigs!?

Exactly.
Too many people have a lot of deluded, pre-biased ideas about a lot of these issues. They read articles about the topics to find facts that support their stance, rather than reading the articles objectively.

no i see it as pointless to argue about it, its fairly obvious that most people are just randomly going on about the difference between ASCR and ESCR, but the point is?

The point is that this is a radical new treatment using a new and unproven branch of science (ESCR) which despite it's controversy has extreme potential for curing the uncurable - like blindness.

Isn't it illegal to kill a fetus in the third-trimester?  I mean the Surpreme Court is today discussing the legality of Partial Birth Abortion.

Also mice develop differently.  Yes I know we use mice to test with, but in this case they are not identical.  I would find this research more promising if we did it with a pig, which is closer to that of a human than a mouse.

If they can get the same results in a pig then this maybe the first embryonic solution.  However, if it requires a baby in the third-trimester to harvest its eyes, then I doubt many people would support it - and its illegal in the United States to abort a fetus in the third-trimester.

I don't know about you, but I would stay blind if it ment that I would kill a fetus in the third-trimester.  By law, in the United States, a baby in the end of the second-trimester can survive outside the womb. 

Even if this research worked from a third-trimester fetus...I don't think it would be adopted by the medical establishment.
