EPFL scientists have now discovered an additional component: chronic inflammation can cause cells to actually change type — here, eye cells turned into skin.

In the journal Biofabrication (Vol 6, No 1), Barbara Lorber, Wen - Kai Hsiao, Ian M Hutchings and Keith R Martin outline a technique for printing new eye cells that could be used to treat sight loss.

While investigating mouse eye cells, Botond Roska and his team at the Friedrich Miescher Institute for Biomedical Research in Basel, Switzerland, noticed that one type behaved unusually in response to movement.

Newly discovered eye cells can warn us that an object is coming nearer, and do so without the brain's help.

Nevertheless, the outcome may pave the way for transplants of stem cell — derived eye cells called photoreceptors, which could dramatically improve vision in people with eye disease if all goes according to plan.

The iPS cells were made by reprogramming skin cells from the woman's arm, then transformed into specialised eye cells to treat age - related macular degeneration (AMD)-- a condition that affects millions of elderly people worldwide and often results in blindness.

A clinical trial investigating a treatment for blindness is under way this winter to evaluate the safety and efficacy of replacing diseased eye cells with stem cells.

What's more, in rodents the two - eye cells hook into sub-cortical areas of the brain such as the amygdala that help process emotion and fear responses, and areas that play a role in an animal's ability to spot salient events in its environment — an approaching cat for instance.

«But these two - eye cells suggest that other types of visual information are just as important — they allow the human species to survive to engage in the complex behaviours.»

Molecules called receptors serve as the heart of the specialized eye cells.

We can then ask whether blood vessels overgrow in the absence of this regulatory pathway; whether overgrowth causes fluid loss from the vessels that in turn causes eye cells to die; and how the eye might try to recover even without any other intervention.

But as the master antioxidant, glutathione helps fight AMD by fighting inflammation on the macula as well as other eye cells.

While you can get some lutein and zeaxanthin from food, research shows that by supplementing with high doses of these nutrients, you can actually rebuild macular pigment receptors, strengthen eye cell membranes and improve your visual acuity.

And dried Montmorency tart cherries are also rich in vitamin A, which is necessary for skin and eye cell growth, and it's vital for a healthy immune system and reproductive system.

Osteonecrosis (bone cell death), retinal degeneration (eye cell death) & neural necrosis (brain cell death) are some of the examples.

«The activity of purine signaling in inducing eye field precursors,» he says, «might be a very useful tool for the culture dish — generation of progenitor cells for a variety of eye cell types.»

If everything looks good, we will have a model of pathological blood vessel growth in hand, and we can get down to the business of seeing whether the proposed therapy helps shut down bad blood vessel growth and protects eye cells.

BABY BLUE Using human eye cells, researchers fashioned an artificial eye surface that could be used to study and test treatments for eye diseases.

These eye nutrients filter harsh, high - energy blue wavelengths of light, helping protect and maintain healthy eye cells, which is translated into a reduced risk of chronic eye diseases, such as macular degeneration and cataracts.

The downside is that people with these eye diseases are losing sight in large part because they're losing a different type of eye cell: the photoreceptors that sense light in the retina.

The volunteers, ranging in age from 20 to 88, received injections under their retina of a particular type of eye cell, retinal pigment epithelium (RPE) cells, which were derived from hESCs in the lab.

These cells are a special type of eye cell that send signals to the brain center responsible for circadian rhythms, our body's daily clock telling our brain when it's day or night.

The researchers plan to delve deeper into the function of the two - eye cells, initially investigating whether there are the same direct connections between two - eye cells and emotion - processing centres as there are in rats.

The DNA within ES cells is the same as that found in adult heart, skin and eye cells, but it exists in a very open form.

Several agents could be placed on or in the eye, including long - lasting drugs that lower eye pressure, or modified virus particles that put new genes inside the eye cells to slow glaucoma damage.

Once we know how this pathway works, and what happens to eye cells when it isn't around, we will conduct some safety experiments to make sure that the therapy we've devised to replace this cell growth pathway, when active in an adult eye, won't harm eye cells.

To do that we will activate the pathway in adults of this zebrafish model using gene manipulation techniques, then test the health of eye cells.
