Results are showcased at 51st Annual Meeting of The Society of Thoracic Surgeons
San Diego, CA – Investigators at The Feinstein Institute for Medical Research have made a medical breakthrough using 3D printing on a MakerBot® Replicator® 2X Experimental 3D Printer to create cartilage designed for tracheal repair or replacement. The results were reported today at the 51st Annual Meeting of The Society of Thoracic Surgeons in San Diego, in a presentation by Todd Goldstein, an investigator at the Feinstein Institute, part of the North Shore-LIJ Health System. This is a first for medical research where regular MakerBot PLA Filament was used to 3D print a custom tracheal scaffolding, which was combined with living cells to create a tracheal segment.

Your trachea, or windpipe, connects the throat and lungs. Air comes in through the windpipe; carbon dioxide goes out.
If it is torn or diseased, surgeons have two ways to fix it. They can remove the damaged part and attach the healthy ends, but there’s only so much slack. Or they can extract some rib cartilage and graft it into the windpipe, which is also made of cartilage. Additional surgery has risks, however. So some patients can’t be helped.

MakerBot Stories | Feinstein Institute for Medical Research
A team of surgeons and scientists at the Feinstein Institute of Medical Research, the research branch of the North Shore-LIJ Health System, has grown cartilage on a 3D printed scaffolding, pointing the way to custom repairs for damaged and diseased tracheas, or windpipes. The cells grow on a scaffolding created from ordinary MakerBot PLA Filament on a MakerBot Replicator 2X Experimental 3D Printer. “3D printing and tissue engineering have the potential to replace lots of different parts of the human body,” says Dr. Lee Smith, a pediatric otolargyngologist who participated in the research. “The potential for creating replacement parts is almost limitless.”
It has been announced, that a novel application of 3D-Bioprinting living tissue models for pharmaceutical testing is being developed at Swansea University-UK. A team of scientists have begun trailing a process, which has been designed to augment the development of new drugs and treatments. The research team led by Dr. Daniel Thomas of the Welsh Centre for Printing and Coating has produced a process which uses precision deposition technologies to produce complex tissue architectures.

Research on various aspects of bioprinting is being conducted at numerous facilities throughout the world. Every part of the globe has begun to provide progressive steps for developing specific aspects of the bioprinting process. One of the newer research facilities is located at the University of Iowa (UI), which is working on tissue engineering. The University’s Mechanical and Industrial Department established its bioprinting lab in 2011.

SAN DIEGO, Nov. 18, 2014 /PRNewswire/ — Organovo Holdings, Inc. (NYSE MKT: ONVO) („Organovo“), a three-dimensional biology company focused on delivering breakthrough 3D bioprinting technology, today announced the full commercial release of the exVive3DTM Human Liver Tissue for preclinical drug discovery testing. Initially, clients will be able to access the technology through Organovo’s contract research services program. This model is intended to provide human-specific data to aid in the prediction of liver tissue toxicity or ADME outcomes in later stage preclinical drug discovery programs.
Organovo’s exVive3D Liver Models are bioprinted, living 3D human liver tissues consisting of primary human hepatocytes, stellate, and endothelial cell types, which are found in native human liver. The exVive3D Liver Models are created using Organovo’s proprietary 3D bioprinting technology that builds functional living tissues containing precise and reproducible architecture. The tissues are functional and stable for at least 42 days, which enables assessment of drug effects over study durations that well beyond those offered by industry-standard 2D liver cell culture systems.
