The Technical University of Munich (TUM) has achieved a groundbreaking milestone in regenerative medicine by successfully developing a “mini-heart” organoid using stem cells. This remarkable achievement offers a new model for studying heart development and diseases, providing valuable insights into early cardiac formation and supporting research into heart-related conditions.
Researchers at TUM, led by Professor Alessandra Moretti, Professor of Regenerative Medicine in Cardiovascular Disease, have induced pluripotent stem cells to mimic the natural process of human heart development. Through a meticulously controlled protocol, around 35,000 cells are spun into a sphere in a centrifuge, creating the organoid. Over several weeks, signaling molecules that simulate the developmental program of the heart are added to the cell culture.
The resulting organoids, approximately half a millimeter in diameter, possess unique characteristics that closely resemble human heart chambers. While they do not pump blood, these “mini-hearts” can contract and respond to electrical stimulation, mirroring the behavior of human hearts. Notably, this is the first time a research team has successfully developed an organoid containing both heart muscle cells (cardiomyocytes) and cells from the outer layer of the heart wall (epicardium), which plays a crucial role in forming heart chambers.
This breakthrough is of significant importance as it provides a model that replicates patient-specific heart conditions, reducing the reliance on animal testing in future drug development. Prof. Alessandra Moretti and her team envision that these personalized organoids could serve as a means to test drugs directly, potentially reducing the need for animal experiments and expediting the drug development process.
Furthermore, the research has led to new discoveries, including the identification of precursor cells involved in heart organoid development. These findings shed light on why the fetal heart has the ability to repair itself, an ability almost absent in adult human hearts. The knowledge gained from studying these cells may pave the way for new treatment methods for heart conditions, including heart attacks.
The potential of organoid research extends beyond the realm of the heart. TUM has established the Center for Organoid Systems, where interdisciplinary research into various organoids, such as pancreas, brain, and heart, will be conducted. This collaborative effort aims to gain insights into organ formation, cancer, and neurodegenerative diseases using state-of-the-art imaging and cellular analysis techniques.
The groundbreaking research conducted by the TUM team has been published in the prestigious journal Nature Biotechnology. The team has also applied for an international patent for the process of creating heart organoids, further highlighting the significance of their findings.
Funding for this study was provided by the European Research Council, underscoring the support and recognition for this groundbreaking research in regenerative medicine.
As scientific advancements continue to push the boundaries of medical research, the “mini-heart” organoid developed by the Technical University of Munich holds immense promise in enhancing our understanding of heart development and diseases. This breakthrough has the potential to revolutionize drug development while minimizing reliance on animal testing, ultimately benefiting millions of patients worldwide.
