A Remarkable New Invention

A remarkable breakthrough, a collaborative team of researchers, led by Professor Yaakov Nahmias from The Hebrew University of Jerusalem, Technion-Israel Institute of Technology, and Tissue Dynamics Ltd., has unveiled a miniature human heart model that could potentially transform drug testing and cardiovascular research. This study, published in Nature Biomedical Engineering, introduces a self-paced multi-chambered human heart model, no larger than a grain of rice, which promises to revolutionize the way we study the heart and its functions.

Cardiovascular diseases remain the leading cause of global mortality, underscoring the critical importance of this pioneering work. Professor Nahmias and his team embarked on an intricate endeavor to create an accurate replica of the human heart using human induced pluripotent stem cells (hiPSCs). The resulting model comprises multiple chambers, pacemaker clusters, epicardial membrane and endocardial lining, all meticulously designed to mimic the structure and functions of the human heart.

One of the most significant features of this heart model is its ability to provide real-time measurements of essential parameters such as oxygen consumption, extracellular field potential, and cardiac contraction. This capability enabled the scientists to gain unprecedented insights into heart function and diseases, making it a game-changer in the field of cardiovascular research.

Advantages of The Heart

Professor Nahmias, Director of the Grass Center for Bioengineering at The Hebrew University of Jerusalem and a fellow of the Royal Society of Medicine and AIMBE, emphasized the significance of their work. “The integration of our complex human heart model with sensors, allowed us to monitor critical physiological parameters in real-time, revealing  intricate mitochondrial dynamics driving cardiac rhythms. It is a new chapter in human physiology”, said Nahmias. Partnering with Tissue Dynamics, the scientists developed a robotic system that can screen 20,000 tiny human hearts in parallel for drug discovery applications. The potential applications of this micro-physiological system are vast, promising to enhance our understanding of heart physiology and accelerate the discovery of safer and more effective pharmaceutical interventions, leading to a healthier future for all.

By offering unparalleled accuracy and insights into cardiovascular diseases, this advanced human heart model has the potential to revolutionize drug testing methodologies. With this tiny heart model, researchers are poised to make significant strides in developing safer and more effective medications for patients worldwide, potentially saving lives and improving patient outcomes.
