Researchers take a step closer to 3D printing living tissues in patients
(LOS ANGELES) – In the TV series Westworld, human body parts are built on robotic frames using 3D printers. While still far from this scenario, 3D printers are being increasingly used in medicine. For example, 3D printing can be used to produce parts of the body such as orthopedic joints and prosthetics, as well as portions of bone, skin and blood vessels. However, the majority of these tissues are created in an apparatus outside of the body and surgically implanted. Such a procedure may involve making large surgical incisions, posing the added risk of infection and increased recovery time for the patient. And since there is a time lapse between when the tissue is created and when it is implanted in the patient, further complications may occur. To prevent these complications, a team of scientists have developed a technology to print tissues directly in the body.
