In 2017, Japanese experts plan to hold the world’s first clinical trial, part of which will be transplanting retinal eye tissue from induced pluripotent stem cells of one person to another. This was stated by representatives of the four research institutions that will participate in the tests.

The project involves the universities of Osaka and Kyoto, RIKEN Research Institute and the Centre for research and application of iPS-cells and the central hospital of the city of Kobe. The operation, which was announced professionals will take place in the treatment of serious eye disease – macular degeneration. This disease affects the central retinal vessels in the area where focused beams of light, and in some cases can lead to blindness, reports nhk.or.jp.
The induced pluripotent stem cells can be obtained from its “normal” cells, using for example a small fragment of the skin with his hand. One of the advantages of this method is the fact that from an ethical point of view, he is considered by many looks much more acceptable than the use of germ cells.
It was about a month ago announced that stem cells derived from skin cells allowed Japanese biologists partially restore the vision of 70-year-old patient suffering from macular degeneration. During the one and a half years after that occurred in 2014. surgery or retinal signs of rejection or any other abnormalities were found, and the sight of women has improved somewhat. However, in this case, the woman used cells. Such cells have a natural way to approach a man perfect, so the first experiments were conducted it with them. However, the preparation of such an operation takes 10 months and large financial costs. If it turns out that donor pluripotent stem cells are just as effective, it will save a considerable amount of valuable time and money.
