TOKYO, June 7 -. RIA Novosti, Ivan Zakharchenko Japanese medical plan in the first half of 2017 to start operations on tissue transplantation from donor stem cells in patients with severe retinal disease – macular degeneration, reported Japanese media <. / p> This is a disease that can lead to blindness, it affects the retinal vessels in the macula area – center, which focused beams of light.

According to the NHK TV channel, the researchers RIKEN Institute and the central hospital in the city of Kobe and Kyoto and Osaka Universities will be able to carry out operations after obtaining permission from the government.
