![]() This amount of cartilage helps the crocodile maintain its movements. The crocodile has a much greater volume of cartilage than other creatures. The 3D bioprinting explant technique, transferring a cell or a piece of tissue from a plant or animal to human body, can potentially replace current methods of joint repairs that require surgery, according to Dr Strappe, “What we’re looking for is a long-term repair to the cartilage so people can return to work and to sport much faster and they don’t have the long-term effects of inflamed joints.” In England and Wales, approximately 160,000 hip and knee replacement surgeries are performed every year. ![]() Nearly 54 million people suffer from arthritis in the U.S. Microbiologist Dr Padraig Strappe with a croc cartilage. The crocodile’s cartilage is rich in proteoglycans, a protein which promotes tissue growth, Dr Strappe explained. ![]() Padraig Strappe, Microbiologist at CQUniversity and leader of this research, “You are left with a hole that needs to be filled in.”Ī 3D bioprint of crocodile cartilage also known as a “soup” can be inserted into the gap to fill the hole. The cartilage has difficulties healing as there is no blood supply to the bone. Microbiologists at Central Queensland University (CQUniversity), Australia, are working to use crocodile protein with healing powers and 3D bioprinting to repair joint damage.Ī traumatic injury to a joint can leave a crack or a hole between a joining bone. ![]()
