A team of researchers, led by Professor Yaakov Nahmias from The Hebrew University of Jerusalem, Technion-Israel Institute of Technology, and Tissue Dynamics Ltd., has made a substantial advancement by producing a miniaturized human heart model that has the prospective to transform cardiovascular research study and drug testing. The research, recently released in the journal Nature Biomedical Engineering, introduces a self-paced multi-chambered human heart model, about the size of a rice grain, which uses a groundbreaking method to studying heart functions.
Heart disease remain the leading cause of worldwide mortality, underscoring the vital significance of this pioneering work. Teacher Nahmias and his group embarked on a complex undertaking to create a precise replica of the human heart utilizing human induced pluripotent stem cells (hiPSCs). The resulting design makes up multiple chambers, pacemaker clusters, epicardial membrane, and endocardial lining, all meticulously designed to mimic the structure and functions of the human heart.

The heart design, approximately the size of half a grain of rice, represents a remarkable feat in heart research and holds immense potential for accuracy drug screening. Currently, the research group has actually made groundbreaking discoveries that were formerly unattainable utilizing traditional methods. Significantly, the heart design unveiled a brand-new form of cardiac arrhythmia, unique from those observed in traditional animal models, thus providing brand-new avenues for studying human physiology.
The ramifications of this discovery extend to the pharmaceutical industry, as it allows scientists to acquire invaluable insights into the precise results of pharmaceutical compounds on the human heart. The heart designs response to the chemotherapeutic drug mitoxantrone, frequently utilized to deal with leukemia and several sclerosis, was thoroughly tested.
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, highlighted the significance of their work. “The integration of our intricate human heart model with sensing units, permitted us to monitor critical physiological criteria in real-time, exposing intricate mitochondrial characteristics driving heart rhythms. It is a brand-new chapter in human physiology,” stated Nahmias.
Partnering with Tissue Dynamics, the scientists established a robotic system that can screen 20,000 tiny human hearts in parallel for drug discovery applications. The possible applications of this micro-physiological system are large, promising to improve our understanding of heart physiology and accelerate the discovery of much safer and more effective pharmaceutical interventions, leading to a much healthier future for all.
