article imageScientists print retinal cells

By Tim Sandle     Dec 21, 2013 in Science
Scientists have printed healthy rat retinal cells using a simple ink-jet printer. They hope this the the first step towards tissue printing.
To produce their print, a research team first shot out and arranged two types of neurons from the retina of rats, the BBC has reported. Having created their pattern, then then proceeded to print out the cellular arrangement using the type of printer found in many homes, schools and offices.
The research team hope that their demonstration marks another advance in the march toward custom-made tissues. The lead scientists behind the printing, Keith Martin and Barbara Lorber from the University of Cambridge, said in a research brief: "Although our results are preliminary and much more work is still required, the aim is to develop this technology for use in retinal repair in the future."
The retina is a complex part of the eye. It is a light-sensitive layer of tissue, lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina (through the cornea and lens) , which serves much the same function as the film in a camera.
The findings have been reported in the journal Biofabrication, in a paper titled "Adult rat retinal ganglion cells and glia can be printed by piezoelectric inkjet printing."
