Scientists say they have been able to successfully print new eye cells that can be used to treat blindness. The journal Biofabrication used animal cells for confirmatory work. The University of Cambridge team said that this paves the way for the growth of retinal light, the light-sensitive layer behind the eye's injured tissues. More tests are required before human trials.
The retina is often a large factor that affects the eye because it is missing or damaged, causing people to stop watching television and seeing the faces of their loved ones. This study is a huge step in the direction of the retina. The results at the moment were preliminary and showed that the printer can print out two types of cells, ganglion cells and glial cells, from adult rats. These cells are sent from eye information to specific parts of the brain and provide support and protection of neuronal cells.
Printed cells maintain long-term activity. Keith Martin and co-authors of Cambridge University, Dr. Keith Martin and Dr. Barbara Lobber and John van Gerst, said: "The loss of nerve cells in the retina is the main cause of many blinding eye diseases. The retina is a kind of Exquisitely organized structure where the precise arrangement of cells in relation to each other is effective."
Scientists have been able to use stem cell transplantation to repair blind mice.
