News Picks : Using inkjet printers to restore sight
19 December 2013
BBC: Retinal cells have been successfully replicated using an inkjet printer. In a study published in the journal Biofabrication, Keith Martin of Cambridge University and colleagues describe how they were able to print two types of cells from the retina of adult rats—ganglion cells and glia. Not only did the printed cells remain healthy, they continued to grow in culture. Nerve-cell loss in the retina is a major cause of blindness. Although much more work is needed before the technique is ready for use on human patients, it is one of a growing number of promising methods to repair the sight-giving cells of the retina.
