Scientists are already growing muscles, bones, and mini-organs in the lab. But these tissues are generally small and simple. That's why two scientists from Oxford University are proposing that we use humanoid robots to grow engineered tissues instead. From a report: Robots dressed in human flesh would benefit people who need tissue transplants, Oxford University researchers have said this week. At present human cells are grown in stationary environments, but moving humanoids could help them develop in a far more healthier way. Robots could "wear" tissue grafts before transplantation, researchers Pierre-Alexis Mouthuy and Andrew Carr propose in the latest issue of Science Robotics. Today sheets of cells are grown in stagnant tanks, but these "fail to mimic the real mechanical environment for cells," say the scientists. The resulting tissues aren't used to moving, stretching and straining, which make them problematic for use by patients.
