Neuroscientists say they have used an inkjet printer to print cells from the eye, making a practical step in the quest to grow replenishment tissue for damaged or diseased organs.
Researchers at England's University of Cambridge extracted two types of cells from rat retinas and sent them through a printer nozzle to see if they survived. The cells remained healthy after being printed, retaining their ability to survive and grow in culture, they reported in the British journal Biofabrication.
The scientists said this is the first time that the technology has been used to successfully print mature cells from the central nervous system. They cautioned, however, that much work lay ahead.
