Exploring Cardiomyocyte and Toxicology Research: Prof. Jürgen Hescheler at the University of Cologne
Share
### Introduction
Prof. Dr. Jürgen Karl-Josef Hescheler is a pioneering figure in stem cell biology and regenerative medicine. As the director of the Institute for Neurophysiology at the University of Cologne, his work over the past three decades has profoundly shaped the understanding of electrophysiology, stem cell differentiation, and safety pharmacology. He’s renowned as the first scientist to perform electrophysiological characterization of embryonic stem‑cell–derived cardiomyocytes and secured Germany’s first permit for human embryonic stem cell research. eBookshelf+12physiologie.uni-koeln.de+12Wikipedia+12
⚙️ Cardiovascular Regeneration & Toxicology: Key Advances
Cardiomyocyte Engineering & Functional Testing
Hescheler’s research explores how human induced pluripotent stem cells (hiPSCs) can differentiate into functional cardiomyocytes. These are foundational for regenerative heart therapies and in-depth cardiotoxicity studies. Notably, he led a 2019 review describing the therapeutic potential of spermatogonial stem cells for cardiac repair: a promising alternative to traditional stem cell types. PubMed
Predicting Drug Effects with iPSC Models
In response to rising clinical concerns about chemotherapy-related cardiotoxicity, Hescheler’s group developed in vitro platforms using hiPSC-derived cardiomyocytes to screen for drug-induced electrophysiological abnormalities. Several high-impact studies addressed mechanisms behind doxorubicin and other compounds by identifying early biomarkers like microRNAs. surgicalpathology.insightconferences.com+14Research.com+14ResearchGate+14
🌐 Leadership in European Stem Cell Consortia
From 2009 onward, Hescheler coordinated major European research consortia addressing stem cell standardization, cryobanking, and in vitro toxicity testing—iPS/bone marrow for cardiac repair, CRYSTAL, ESNATS, and DETECTIVE. He also founded and continues to chair the German Society for Stem Cell Research (GSZ), which supports research exchange and education nationwide. Wikipedia+2physiologie.uni-koeln.de+2Wikipedia+2
His labs also participate in FunGenES, focusing on functional genomics of engineered embryonic stem cell lines, shaping regulatory and safety frameworks across Europe. physiologie.uni-koeln.de
