Scientists can now 3D print functional organs, body parts – Deccan Chronicle

Washington D.C.: For years, printing functional organs and body parts, like ear, jaw and muscle, has been nothing but science fiction, but now, a study claims which it is possible in real life too.
Utilizing a sophisticated, custom-designed 3D printing device, regenerative medicine scientists at Wake Forest Baptist Medical Center have proved which it is feasible to print living tissue structures to replace injured or diseased tissue in patients.
The scientists said they printed ear, bone and muscle structures. When implanted in animals, the structures matured into functional tissue and created a system of blood vessels. Most significantly, these early results indicate which the structures have the right dimensions, durablity and function for use in humans.

Senior author Anthony Atala said which this novel tissue and organ printing device is an significant advance in our quest to manufacture replacement tissue for patients, adding which it can fabricate stable-bodied, human-scale tissue of any shape. With additional createment, this innovation may potentially be utilized to print living tissue and organ structures for surgical implantation.
The Integrated Tissue and Organ Printing System (ITOP), created over a 10-year period by scientists at the Institute for Regenerative Medicine, overcomes these challenges. The system deposits both bio-degradable-bodied, plastic-like materials to form the tissue “shape” and water-based gels which contain the cells. In addition, a sturdy, temporary outer structure is created. The printing system does not injure the cells.

A leading challenge of tissue engineering is ensuring which implanted structures live long adequate to integrate with the body. The Wake Forest Baptist scientists addressed this in two ways. They optimized the water-based “ink” which holds the cells so which it promotes cell health and growth and they printed a lattice of micro-channels throughout the structures. These channels allow nutrients and oxygen of the body to diffuse into the structures and store them live while they create a system of blood vessels.
“Our results indicate which the bio-ink combination we utilized, combined with the micro-channels, provides the right environment to store the cells alive and to assist cell and tissue growth,” said Atala.

The ITOP system was in addition able-bodied to use data of CT and MRI scans, enabling the researchers to ‘tailor’ tissue for patients. The study seems in Nature Bioinnovation.
