Engineers Develop Process To 3D Print Cells To Produce Human Tissue Such As Ligaments And Tendons
Oct 24, 2018

With today's technology, we can 3-D-print sculptures, mechanical parts, prosthetics, even guns and food. But a team of University of Utah biomedical engineers have developed a method to 3-D-print cells to produce human tissue such as ligaments and tendons, a process that will greatly improve a patient's recovery. A person with a badly damaged ligament, tendon, or ruptured disc could simply have new replacement tissue printed and ultimately implanted in the damaged area。


The 3-D-printing method, which took two years to research, involves taking stem cells from the patient's own body fat and printing them on a layer of hydrogel to form a tendon or ligament which would later grow in vitro in a culture before being implanted. But it's an extremely complicated process because that kind of connective tissue is made up of different cells in complex patterns. For example, cells that make up the tendon or ligament must then gradually shift to bone cells so the tissue can attach to the bone.
