Photos: Muscles and Bones Made with New ‘Bioprinter’

A fresh 3D printer can print living tissue structures that could one day be utilized to replace injured or diseased tissue in patients.”With additional development, this technology could possibly be utilized to print living tissue and organ structures for surgical implantation,” Dr. Anthony Atala, director of the Wake Forest Institute for Regenerative Medicine, who coauthored a study describing the new printer, said in a statement.

In experiments, the researchers planted such ear structures under the skin of mice to see whether the structure tissue would live. They found that the structures did live, and had even grown blood vessels by two months after implantation, thanks to unique routes printed through the constructions.

The shape and size of the fragment corresponds to the shape and size of fragments which could be used for jaw reconstruction in human patients.

The brand new printing system can use information from CT and MRI scans to tailor make tissue for patients. For example, if a patient is missing an ear, the printer could print a fresh identical ear arrangement based on a scan of their whole ear.

The brand new printer deposits plastic-like substances to form the shape of the tissue and water-based gels which contain cells. This procedure enables the printed tissue to keep its shape and ensures the printing procedure will not damage the cells.

The brand new printer enables researchers to print tissue and organ structures which are bigger and more powerful in relation to the comparatively easy and delicate tissues that researchers have engineered before.

Up to now, the researchers have been able to plant just a number of the tissue and bone structures they’ve made into rodents. A great deal more research is necessary before these structures could be planted in human patients, the researchers said. (Credit: Wake Forest Institute for Regenerative Medicine)
