Blindness treatment by transplantation of the eye is becoming more realistic possibility - for the first time scientists managed to grow the retina of the eye in the laboratory.
Researchers was surprised when they noticed how stem cells are situated in a spontaneous laboratory test tube to a complex structure, reminiscent of the developing embryonic eye. It is hoped that eventually the entire retina will produce and it will be transplanted to people with low vision or blind.
Japan physics and scientists of chemistry research institute first produced embryonic stem cells in the laboratory test tube, then added a mixture of proteins that they continue to grow. They hoped to produce a specific organ, but still was stunned when after 10 days cells began to group and form retina. Test results showed that the cells are grown to function and interact with each other normally.
The experiment was carried out with the mouse eye, but scientists believe that the human eye can be similarly raised too. Medics hope that clinical trials of retinal transplantation will be open to perform within the next decade.
