Innervated human cardiac muscle model reveals sympathetic drivers of KCNH2-associated arrhythmias

Describes a human 3D innervated cardiac tissue model combining sympathetic trunk–patterned neural organoids with iPSC cardiomyocytes to study neurocardiac interactions and arrhythmia drivers.

Key Takeaways
  • Human tissue engineering in combination with induced pluripotent stem cells (iPSCs)
  • Number of tissue-engineered and organoid models of brain 14
  • Design principle in heart models is the co-culture of CMs with non-myocytes
