Toward a 3D printed heart

FacebooktwitterlinkedinFacebooktwitterlinkedin

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.
