Stem Cell Treatment To Cure the Most Common Cause of Blindness
The Times Online reports that researchers from the Institute of Ophthalmology at University College London and Moorfields eye hospital have developed stem cell therapy that can treat age-related macular degeneration (AMD), the most common cause of blindness. They are currently moving the treatment through the regulatory approval process, and clinical trials are expected to start within two years. Quoting:
"Under the new treatment, embryonic stem cells are transformed into replicas of the missing cells. They are then placed on an artificial membrane which is inserted in the back of the retina. ... [Professor Pete Coffey, director of the London Project to Cure Blindness] said the treatment would take 'less than an hour, so it really could be considered as an outpatient procedure. We are trying to get it out as a common therapy.'
But don't let this discourage any mad scientist from creating ocular implants, especially ones with wifi and defensive laser beams.
I feel sorry for Larry Niven. Back in the 1960s and 1970s he was writing works of science fiction (e.g. the Gilm 'The Arm' Hamilton stories in Flatlander ) that suggested that organ transplants were going to be so widespread as a cure that even the most minor crimes would get the death penalty. Instead, it looks like the human race may realize stem cell cures faster than anyone could have imagined. Oh, and Kurzweil suggests we'll all be in robot bodies before the century's end, so those great hard science fiction writers of half a century ago fall even further behind.

Although the article does not mention what kind of cells and membranes are transplanted and wether it is going to be used in exsudative or non-exsudative AMD I would assume that it's retinal Pigment Epithelium and Bruch's Membrane being used in wet (= exsudative) AMD.
Therefore this seems to involve subretinal surgery, which is not a piece of cake and usually diminishes visual accuity.
Previous attempts in this direction have already been done (macular rotation, retinal pigment epithelium transplants, etc.), results have not been all too gratifying.
Reading the article, is hardly ready for use, so far only tested on rats and pigs. There'll be many years of trials before its ready for use on people. Plus Stem cells have be known to turn cancerous, cancer of the retina, would be quickly fatal, there so close to the brain.
Stem cells have tremendous potential to cure disease and even to reverse the aging process. The next twenty years of research might total change the sad process of aging in human.

Commodore64_love: I don't comprehend people who're so frightened of death that they'll bankrupt themselves to stay alive
Someone tag this !porn because I was seriously confused for a minute.
I just don't see how taking the life of an embryo so that the older or sick can keep on living is anything other than vampirisim (in a loose sense of the word, or course).
Erm, someone correct me if I'm wrong but hasn't this been discussed time and time again. Embryos for stem cell research are not bred just for the purpose of being "killed". The cells, at least acording to what I've heard/read (again, prove me wrong if you know any better, I'm not a professional) are taken from embryos that were fertilized for the purposes of fertility treatment/artificial impregantion. During those treatments multiple embryos are fertilized and some of them are the discared. The stem cells are extracted from discarded embryos. This means that the embryos would "die" anyway and at least this way they're being used for something beneficial.
Moreover, I don't understand the problem at all. Embryos aren't humans. They are clusters of cells. They are by no means sentient or intelligent. So what's the whole deal about "vapirism"? People donate blood and organs all the time - this is not so far from it. Bottom line is: The embryo is alive in the sense all cells are alive but it has no "life" to be taken away. If you seriously think that way I suggest you stop eating any food because by eating vegetables you're basically taking the life of another organism so that you can live and according to you, that's "vampirism".
