Carnegie Mellon ‘s Adam Feinberg is developing 3D printing techniques that could in the future be used to repair the heart . This work is aimed at alternative solutions for the 4,000 Americans currently waiting to receive a heart transplant.
Feinberg described his progress: “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.”
The next step is to incorporate real heart cells into these 3-D printed tissue structures, providing a scaffold to help form contractile muscle.
