PRINTING EYE CELLS TO HELP CURE BLINDNESS
Scientists recently printed new eye cells, paving the way to cure some types of blindness in humans.
Their research, which used animal cells to test the concept, is the first step towards producing tissue implants.
British researchers used inkjet printers to print two types of central nervous system cells from the retina of adult rats - ganglion cells and glial cells.
Retinal ganglion cells transmit information from the eye to certain parts of the brain and glial cells provide support and protection for neurons.
The study, by the University of Cambridge, found that printed cells were able to grow normally and can be kept healthy but more tests are needed before human trials can begin.
