Protect yourself against vision loss

May 30, 2017

This article is from Phil Rego:

Using stem cells to regenerate healthy cells in disease-damaged eyes is the holy grail for researchers. This is especially true for incurable conditions that damage the retina, the layer of light-sensitive cells at the back of the eye.

Earlier this year, a Japanese man became the first person to receive retinal stem cells created from donated skin cells to stop his macular degeneration from getting worse.

And scientists at the Jules Stein Eye Institute at the University of California at Los Angeles report promising results from transplanting stem cells from embryonic cells into patients who had been blind for decades from AMD and another disease. A study in 2014 reported that 10 of the 18 patients who received the cells experienced significantly improved vision.

Japan to begin transplants using donor iPS cells

June 12, 2016

This news is from Lauren Tappan:

Four Japanese institutions will collaborate on transplanting tissue grown from induced pluripotent stem cells taken from donors into patients suffering from age-related macular degeneration, a hard-to-cure eye disease.

The initiative, announced Monday, will break new ground in that the cost of transplanting iPS-derived tissue will be significantly reduced by using stocked cells provided by donors, instead of using the patients’ own cells as in a previous case involving a sufferer of the same disease.

Under the partnership agreed on May 30, Kyoto University will provide iPS cells resistant to immunological rejection in the treatment and the government-affiliated Riken research institute will grow them into retinal cells. Osaka University and the Kobe City Medical Center General Hospital will implant these cells into patients as early as the first half of 2017.

The cost is approx. $1 million.

Marlborough Company Looks to Regrow Cells in the Eye

August 22, 2015

Instead of treating symptoms of macular degeneration, a leading cause of blindness, a Marlborough company is looking to figure out how to regrow eye cells that cause it.

The Boston Business Journal reports that Ocata is starting patient trials within the next month and a half to repeat the results of a smaller trial that “attracted worldwide attention last year.”

In the trial, Ocata’s stem cells were used in eye cells of 18 patients with macular degeneration, and it helped improve vision in 10 of the patients.

The Uncertainty of Stem Cell Treatments

June 5, 2015

For almost a decade, stem cell treatment has held out hope as a treatment for macular degeneration. Hope, but not FDA approved certainty.

Popular Science magazine has just written an article titled ARE NEW STEM CELL THERAPIES MIRACLES IN A BOTTLE–OR JUST A DANGEROUS FORM OF SNAKE OIL?

Their review is mixed and full of unknowns. Some wonderful successes and some failures. Leigh Turner, an associate professor at the University of Minnesota’s Center for Bioethics, finds the various SVF therapies dubious. “No one has proved they’re safe or effective,” he says. “People are paying a lot of money for these treatments without any assurances.”

After 7 years of chronic back pain, the author was”cured” after a single treatment. But he still worries about recurrence. When you sign up to be a guinea pig, nothing is certain, and only time will tell.

Stem cell therapy success for macular degeneration

October 18, 2014

The study (pdf) represents the first evidence for the long-term safety of the pioneering therapy, which restored some vision to more than half of the patients who took part in the trial.

There had been concerns that the cells could be rejected by the body’s immune system or become overactive and grow into tumours. But after following the patients for up to three years, researchers said the treatment appeared to be safe.

The trial focused on 18 patients with two different types of macular degeneration (9 with Stargardt’s, 9 with dry AMD ). The diseases have no effective treatments and are among the leading causes of blindness in adults and children in the developed world.

Effectiveness is yet to be proven.

Hope for blind as scientists find stem cell reservoir in human eye

October 4, 2014

Scientists at the University of Southampton have discovered stem cells in the human eye which can be transformed into light sensitive cells and potentially reverse blindness. The reservoir of stem cells is in an area of the eye called the corneal limbus. It could offer a potential cure for the hundreds of thousands of people suffering macular degeneration or retinitis pigmentosa, which are both caused by the loss of photo-receptor cells in the eye.
