Study Finds Weight Loss Drug Reduces Heart Muscle Size
A study from the University of Alberta suggests that the weight loss drug semaglutide, known for reducing body weight, may also shrink heart muscle mass in both mice and lab-grown human heart cells. While the drug did not affect heart function in the short term, it caused significant muscle loss, raising concerns about potential long-term health impacts, such as decreased immunity and increased cardiovascular risks. The findings highlight the need for further research to confirm these effects in humans, especially given the drug's growing use.
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.
Ink Innovation: 3D-Printed Heart Muscle Beats with Fiber-Infused Ink
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a new hydrogel ink infused with gelatin fibers that enables 3D printing of a functional heart ventricle that mimics beating like a human heart. The fiber-infused gel ink allows heart muscle cells to align and beat in coordination, opening up possibilities for creating better in vitro platforms for drug testing and evaluating treatments for heart disease. The technique could also be used to build heart valves and other complex heart structures.
