Old age is bliss. There’s a nest egg in the bank account and nothing needs to be done but spoil the grandchildren and watch Judge Judy. But, like a bad episode of the Twilight Zone, age-related macular degeneration (AMD) sets in and eyesight begins to fade until the grandchildren all look the same and the television turns into a bright looking radio. Such a cruel fate may soon be avoided if the London Project is successful in using stem cells to cure age-related blindness. It seems that science has again found itself at odds with humor, eventually making extinct jokes about old-people’s driving habits.
Now you see it, now you don't
Age-related macular degeneration is a common ailment among the elderly, affecting 10 percent of the population within the ages of 65 to 74. As the body ages, the support structure for the rods and cones within the eye, called retinal pigment epithelial (RPE) cells, begin to thin and eventually cause the light-sensitive cells to die, leading to blindness. The London Project (a consortium of scientists from the University College in London, Sheffield University, and the Moorfields Eye Hospital) thinks they have a cure for this degenerative disease, set to pass clinical trials in 3 years time, by injecting RPE cells back into the eye.
This is accomplished by using embryonic stem cells to create new RPE cells in the laboratory and then surgically transplanting them into the patient’s eye. The new cells will augment the already existing RPE cell network and thus restore vision. Scientists at the London Project are hoping that, once perfected, RPE therapy will be a commonplace outpatient procedure, lasting only about 45 minutes.
Like a black hole in your eye
The project already has the backing of Pfizer, which would be able to supply doctors and clinics with a constant supply of RPE cells, and 4 million British Pounds ($6.12 million) of financing from an anonymous donor within the United States. Clinical trials are expected to be complete in Europe by 2011, with the procedure being offered to the general public shortly thereafter. Due to the stickiness of the stem cell debate in the United States, it is unclear on how much longer it would take before the procedure is available in North America.
The cure for blindness is not necessarily a novel quest. Here at Singularity Hub, we have reported on some technological breakthroughs that may lead to restored sight, including gene therapy, implantable telescopes, and bionic eyes. But stem cells are seen by many as the golden cure to a great number of diseases. This stem cell based clinical trial goes to show that this is not just a futuristic fix for that which ails humanity, but a tangible reality that may be commonplace in a scant few years time.
Stem cells are here; there’s no doubt about it. Over the next few years, as theoretical claims turn into scientific evidence, it will be hard to deny the life-extending power that lies in these formative cells. Currently, though, stem cells are mired in an ethical battle that extends beyond the laboratory bench and into the halls of congress. While Europe may not have any qualms with stem cell therapy, we here in the United States may need to be patient, for the only thing congress has ever done quickly was lull its constituents to sleep.

I suppose those people BORN with mutations in their DNA will have to have more stem cell sessions as thier DNA will destroy any GOOD this new stem cell technology will bring. Will it be affordable ?
It’s both funny and sad that the country responsible for pretty much all the science in the 20th century wants to keep the 20th century technology in place and tries to shun the 21st century.
And as for Advanced Cell Technology, if they had good technology, why has their stock price been on a downward slide since their IPO? Their announcement of their RPE technology resulted in… no stock activity. Considering they claim there’s a $28 billion dollar market related to AMD to be captured, you’d think their technology might make their company worth more than 15 cents a share. Since they’re a public company, no stock worth = little ability to borrow money to capitalize on their inventions.
This London Consortium is set to complete their clinical trials in 3 years time, not start them. It’s privately funded and not a for-profit business. ACT will have to turn a profit to be able to bring these technologies to market, and their current stock situation makes that look like a vanishingly small prospect. Their 52-week low on stock was 1 penny.
Also, I would like to point out that ACTs own website claims they were filing for an IND LAST year. And their website still says copyright 2006. If they can’t keep their quite simple website up to date, why should I trust them sticking cells in my eyes?
They also mix “have completed” and “will be able to” in subsequent sentences describing their technology. To wit: “Applying appropriate controls as specified in the FDA’s cGMP regulations, ACT staff was able to produce master and working cell banks of human embryonic stem cells. In working out a controlled, compliant manufacturing methodology, an unlimited amount of RPE cells can be derived by ACT for clinical use.”
They say they have produced cell banks, and that an unlimited amount of RPE cells can be derived. Not have been, just “can be.”
Smells like hyperbole to me!

Well there are 100 trillion cells in the body and they all communicate with each other to produce our miracle existance. Sure not even embryonic stem cells will be the ANSWER to diseased states in humans and sure they publish untruths or stretch the TRUTH of their human trials…but what other HOPE is there for people ? MONEY is the evil of this experimentation and big companies and Governments are waiting more anxiously than most.
Would you prefer to wait for microscopic lenses with pixels and learning to SEE again.?.
Advanced Cell Technology is 2-3 years ahead in the RPE research.
The London Project and Pfizer just started.
You should research your topic a bit more before publishing, showing all the leading players in the game.

Andrew,
I’m not entirely sure where you are located but I might suggest looking at a company in the US; Advanced Cell Technology. They are going to file an IND with the FDA in June/July for trials in humans using RPE cells (injected into the eye).
Thanks.
