Bioprinting Full-Scale Hearts with Stem Cells

Posted by on Aug 14, 2019 11:01:00 AM


collagen-heart-parts-2Researchers at Carnegie Mellon University are combining stem cells and collagen to create organized printed structures that could be assembled into full-sized hearts. The breakthrough here involves the ability to keep the collagen in the desired shape throughout the printing process, since it initially deposits as a liquid. The researchers used a new hydrogel to temporarily support the deposited collagen, and then easily removed the gel by heating the structure to room temperature. The researchers also used 3D imaging to create valves, ventricles and blood vessels, seeding them with stem cells to then be assembled into full-sized hearts.

This technique is poised to change how doctors approach heart replacements and repairs required due to heart attacks or congenital defects. "By using MRI data of a human heart, we were able to accurately reproduce patient-specific anatomical structure and 3D bioprint collagen and human heart cells,” says Professor Adam Feinberg, who conducted this research.

This innovative research demonstrates the integral role stem cells are playing in cutting edge medical care options. By banking their own valuable stem cells, families can ensure that they will have access to these emerging therapies in the near future.
