The Challenge of traditional Bioprinting
Three-dimensional bioprinted tissues have emerged as a promising tool for repairing damaged heart tissue. Thes tissues, composed of cells and body-compatible materials, hold immense potential. However, a notable limitation has been their inability to generate the necessary electrical activity for cellular function. Traditionally, this has required invasive methods, such as wire and electrode placement, which can damage surrounding tissues and limit therapeutic efficacy. A Light-Driven Solution
The research team, led by Y. Shrike Zhang, PhD, of the Division of Engineering in Medicine at Brigham and Women’s Hospital, addressed this challenge by developing an optoelectronically active ink. This ink, when incorporated into bioprinted tissues, can be remotely stimulated by light to generate electrical activity. “We showed for the first time that with this optoelectronically active ink, we can print scaffolds that allow remote control of engineered heart tissues,” said zhang. “This approach paves the way for non-invasive light stimulation, tissue regeneration, and host integration capabilities in cardiac therapy and beyond.” Proof of Concept and Future Directions
In preclinical models,the team demonstrated that these light-activated tissues could synchronize with and accelerate the heart rate when stimulated. This proof-of-concept marks a significant step forward in cardiac therapy.”Now that we have established the proof-of-concept for this technology,we are shifting our efforts towards understanding how it might promote long-term tissue regeneration and integrating it seamlessly within the heart’s biology,” Zhang added.Key Advancements at a Glance
