3D Printing Heart Tissue

3D printing tissue gel heart arteries in a soft gel substrate using a syringe as an extrusion nozzle shows the possibility to print living tissues in the same manner.

As of this month, over 4,000 Americans are on the waiting list to receive a heart transplant. With failing hearts, these patients have no other options; heart tissue, unlike other parts of the body, is unable to heal itself once it is damaged. Fortunately, recent work by a group at Carnegie Mellon could one day lead to a world in which transplants are no longer necessary to repair damaged organs.

“We’ve been able to take MRI images of coronary arteries and 3-D images of embryonic hearts and 3-D bioprint them with unprecedented resolution and quality out of very soft materials like collagens, alginates and fibrins,” said Adam Feinberg, an associate professor of Materials Science and Engineering and Biomedical Engineering at Carnegie Mellon University. Feinberg leads the Regenerative Biomaterials and Therapeutics Group, and the group’s study was published in the October 23 issue of the journal Science Advances.
