The research, published in the journal Nature, indicates that the retina was created by the persuasion of embryonic stem cells of mouse in a precise three-dimensional mounting, which made him the more complex fabric designed so far.
The success of this play is that the retina is a highly sophisticated tissue consists of different cell types and has a complex network of connections between them, the researchers said.
Japanese researchers separated the cells and the right mix of nutrients made them grow into a synthetic retina, surprised to see how the cells themselves were organized with little intervention from them.
Although the technique published Thursday in Nature can be adapted to human cells and proven safe for transplantation, it would take years to offer it to replace a damaged retina. However, the development of this tissue paves the way to achieve it.
A biotechnology company U.S. and got a license to begin human trials for treatment of blindness.
However, in the immediate, synthetic retina could help scientists study diseases of the eye and to identify appropriate therapies to treat them.
For the scientific community in the world, this is a great discovery. "There is nothing like this," said Robin Ali, human molecular geneticist at the Institute of Ophthalmology in London, who was not involved in the study.
This work could serve as guidance for the development of other organs, Brice said Conklin, a biologist at the Gladstone Institute of Cardiovascular Disease in San Francisco, who also participated in the investigation.
