Printing human organs is not quite as science fiction as it sounds. A number of bio-technology companies are working on different approaches, which aim to use a patient’s own cells make new tissue and With a global shortage of organs suitable for transplant into critically ill patients, some researchers are looking at 3D printing of living tissue as a solution – but to do it they might need to go into orbit. The ability to transplant tissues made from the injured person’s own cells would be hugely beneficial. Recreating the full function of an organ – the synchronicity of the heart’s action, for example, or the filtration function of a kidney – is no easy thing. DO you think a 3D Printed organ can withstand gravity
