In a small experiment, it was found that vision problems can be restored by a simple transplant of nerve cells into the eye. The experiment was conducted by a team of researchers who belonged to the University College London.
The researchers conducted the experiment over mice born with night blindness. It has been informed that for the experiment, the researchers injected 200,000 immature versions of cells, which is also called rod-photoreceptors, into the mice with genetic condition responsible for making mice blind.
The rod-photoreceptors were taken from healthy mice. When the rod-photoreceptors were injected into the eyes of mice, some of the cells initiated nerve connection. The connection thus formed helped the researchers in regulating their way in a maze in low light. Thus, the vision problem of the mice was restored.
The findings of the researchers have been published in the journal Nature. It has been informed that it will take five to 10 years to make the trail available for humans. In the journal, the researchers wrote, "The results presented here demonstrate for the first time that transplanted rod-photoreceptor precursors can integrate into a dysfunctional adult retina, and, by directly connecting with the host retinal circuitry, truly improve vision".
The Director of University College London, Professor Phil Luthert has acknowledged the findings by saying that the study would help in curing various vision problems experienced by humans.
However, humans would be required to wait for five to 10 years as further studies in this regard are required to be conducted. All the pros and cons of the trail should be kept in mind while introducing the treatment to the humans. It has come to light that the study was funded by the Medical Research Council, the Wellcome Trust, the Royal Society the British Retinitis Pigmentosa Society, Alcon Research Institute and The Miller's Trust.
