A growing body of evidence suggests that some of the pigmented cells that make up the iris and other parts of our eyes may be more likely to be associated with cancers than the surrounding cells.
The new study published online by the journal Cell suggests that pigmented skin cells in some people have a higher chance of being associated with cancer.
Researchers looked at 3,300 patients who were diagnosed with retinitis pigmentosa (RP), a type of macular degeneration that causes vision loss and blindness.
The study was funded by the National Institutes of Health and was led by researchers at Emory University in Atlanta.
The researchers found that people with RP had a lower risk of developing cancer than people with normal vision.
They also found that those with RP were more likely than people without RP to have a genetic predisposition to the disease.
Researchers say the results offer some hope that the risk of melanoma, which causes melanoma in red and green eyes, is less severe in people with pigment in their eyes.
But while pigmented cell types are not new, the study raises questions about how much is known about how they may interact with cancer cells.
Pigment in skin cells is not necessarily toxic, but some studies have shown that they can cause cancer in laboratory animals.PIGMENT CellsIn early August, researchers in Germany reported finding cells in the skin of people with cancer that were similar to the ones found in human cancer cells, including some that were more closely related to cancer cells than others.
That finding raised questions about whether these cells were being mutated by cancer cells and whether the cells could potentially be cancerous.
The team found a similar set of cells in pigmentation cells from people with other types of melanomas.
“The finding is very exciting, but it is important to know that this is not the only possibility,” said lead author Dr. Thomas Ries, a biochemist at the University of Tübingen.
“In addition, we don’t know if the cells are actually cancerous or not.”
“We’re not sure yet how we might be able to figure out whether these pigmented stem cells are indeed the cancer cells or not,” he said.
The study also raised questions whether some of these pigments may help identify certain cancers.
“It’s important to understand the impact of this on people’s overall risk of getting melanoma or other types the skin cancers,” said Dr. Daniel Bausch, a dermatologist at the New York University Langone Medical Center and a co-author of the study.
Bausch is not aware of any new studies that have looked at pigmented melanoma cells.
The researchers noted that they are also not certain that the pigments they found were the same ones that would help determine whether people with melanoma are at increased risk for cancer.
Pigs and melanomaScientists are not sure why pigmented pigment cells are more likely or likely to cause melanoma.
However, Dr. Richard Gelles, an oncologist at Emrys University in Oxford, England, said he thinks it’s likely the pigmentation helps protect the skin from ultraviolet radiation and other chemicals that may cause cancer.
Gelles and other scientists have studied pigmented cancer cells in vitro.
They found that pigment cells can make proteins that help fight cancer cells by stopping them from multiplying and replicating.
“There is some evidence that these proteins might be involved in a few types of cancers that have been shown to be more prone to growth,” he told NBC News.
Geles said that it’s possible that pigments could help protect the pigment cells from the sun.
“We have seen that the pigment in the retina is particularly vulnerable to UV radiation,” he explained.
“So I think there is some potential there.”
Gellers said the research also has implications for the melanoma patients that he works with.
“They are not looking for cancer, they are looking for some sort of damage to their skin,” he noted.
“But the pigment in the pig’s eye is one of the things that is being damaged.”
A common type of melanocyteIn recent years, researchers have been exploring the effects of pigmented pigments on melanoma cell growth.
“One of the exciting discoveries is that the melanocytes in the eyes of people are much more sensitive to UV than the normal cells in their body,” Dr. David A. Smith, an immunologist at Johns Hopkins University School of Medicine in Baltimore, told The Associated Press.
Smith said that researchers have found that in addition to pigmented photopigment, the pigment also has an impact on the melanocytic process, which involves the formation of new melanocytes.
The melanocysts are small and have a large, spherical structure, and are important in controlling the proliferation of other cells, such as melanocytes that line blood vessels and hair follicles.
But the process of melanocy
