American scientists from the Medical school at Johns Hopkins made a discovery, which in the future will help patients with diseases of the eye to restore sight. They raised the retina from stem cells in the laboratory. The body responds to light and performs its basic functions. The results of the experiment are described and published in Nature Communications.
The first such experiment has been conducted by scientists from Japan. It happened in 2011, when scientists first raised the retina of the mouse, and then the retina of a person. In the current experiment failed to create "seers" of the retina that respond to light. Scientists note that their body does not differ from the retina of the embryo at 28 weeks of development.
In the future, scientists plan to grow bioengineered retina stem cells from the patients and transplanted in place of the diseased retina.
