NEW YORK (Reuters Health) - US scientists have recently been able to produce eye retinas based on stem cells, hoping that the clinical trial will help future eye patients and give hope to those with visual impairment.
Researchers from John Jones Hopkins in Maryland said they wanted to know how stem cells help human eyes see colors.
According to the study published in the journal "Science", the medical examination may lead to the development of new treatments and revolutionary for some eye diseases such as degenerative macular degeneration, which affects the elderly usually due to damage to the retina.
Most of the medical research on the former was conducted based on experiments on mice and fish, so their results were not accurate due to the different human eye and complexity of the system.
Because the results based on these animal samples are not accurate, scientists have tried to develop an eye retina of human stem cells.
The researchers focused on cells that allow humans to see blue, red, and green, as these colors play a key role in human vision.
The study's purpose is to monitor the path taken by the cells responsible for Ibsar Alwan, and to give a different view of what happens to other mammals, according to the study's co-author, Chiara Eldard.
During this complex process, the researchers found that these cells grow gradually. Initially, the objects responsible for the blue sensor emerge, and then those responsible for red and green come later.
The study found that the lack of thyroid hormones affect these cells. Therefore, children who are deficient in this hormone at birth are more likely to have visual disturbances.
