Revolutionary Ink Enables 3D-Printed Heart Muscle to Pulse
Researchers have developed a technique to 3D print heart muscle that can contract similarly to a human heart's ventricle. By infusing a hydrogel with gelatin fibers and using Rotary Jet-Spinning technology, a patterned structure was created, allowing cardiomyocytes to align and create a cardiac muscle capable of organized contraction. This advancement could lead to replacements for damaged cardiac muscle and other large structures of the heart.
