Naturally, this robotic conditioning would be most useful for higher-quality transplants. You could even personalize transplants by modifying the robot to reflect a patient's anatomy. However, the Oxford team sees other uses. It could reduce the use of animal testing in pre-clinical trials, and could even represent a step toward "biohybrid humanoids" that combine real tissue with mechanical systems. We're not so sure people are looking forward to that last part (it sounds like the background for a Terminator movie), but the discovery is great news overall for burn victims and others who need transplants. Instead of waiting weeks for replacements to grow on their own bodies, they could have doctors print transplants that get a robotic shakedown in a much shorter time.
