Insights

Human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) show promise for drug testing but exhibit significant electrophysiological heterogeneity. This variability, worsened by experimental methods, hinders accurate patient-specific cardiovascular disease modeling.

Area of Science:

  • Cardiology
  • Stem Cell Biology
  • Pharmacology

Background:

  • Human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) are valuable in vitro models for drug cardiotoxicity and personalized cardiovascular disease research.
  • Electrophysiological heterogeneity among iPSC-CMs currently limits the depth of experimental insights and translational potential.
  • Understanding and mitigating this heterogeneity is crucial for advancing iPSC-CM applications.

Purpose of the Study:

  • To review the sources and consequences of electrophysiological heterogeneity in iPSC-CMs.
  • To highlight how experimental artifacts, particularly from patch-clamp techniques, exacerbate this heterogeneity.
  • To discuss the implications of iPSC-CM heterogeneity for developing digital twins of patient-derived cardiomyocytes.

Main Methods:

  • Literature review and critical analysis of existing studies on iPSC-CM electrophysiology.
  • Examination of experimental methodologies, focusing on patch-clamp techniques (manual and automated).
  • Discussion of intrinsic and extrinsic factors contributing to cellular variability.

Main Results:

  • Significant electrophysiological heterogeneity is prevalent in iPSC-CM literature.
  • Patch-clamp artifacts, in both manual and automated setups, demonstrably worsen iPSC-CM heterogeneity.
  • Both intrinsic cellular properties and extrinsic experimental conditions contribute to observed variability.

Conclusions:

  • Electrophysiological heterogeneity is a major challenge for iPSC-CMs, impacting their utility as in vitro models.
  • Standardization of experimental protocols and artifact mitigation are essential to improve iPSC-CM reliability.
  • Addressing heterogeneity is critical for the successful development of patient-specific digital twin models for cardiovascular research.

Electromagnetic Fields01:30

Electromagnetic Fields

Electric fields generated by static charges, often referred to as electrostatic fields, are characteristically different from electric fields created by time-varying magnetic fields. While the former is a conservative field, implying that no net work is done on a test charge if it goes around in a complete loop in the field, the latter is, by definition, not a conservative field; net work is done, and it is proportional to the rate of change of magnetic flux.
However, the observation of Gauss's...
Structure of Cardiac Muscles01:13

Structure of Cardiac Muscles

Cardiac muscle, or myocardium, is a specialized type of muscle found exclusively in the heart. Its unique structural and functional characteristics enable the heart to perform its vital role of pumping blood throughout the body continuously and rhythmically. The cardiac muscle cells, or cardiomyocytes, possess an endomysium and perimysium but do not have an epimysium.
Compared to skeletal muscles, cardiac muscle cells are small and mostly have a single nucleus. Additionally, they are usually...
Specialized Characteristics of Cardiac Muscles01:27

Specialized Characteristics of Cardiac Muscles

The primary role of cardiac muscles is to propel blood throughout the cardiovascular system. The cardiac muscle cells, or cardiomyocytes, exhibit specialized characteristics that allow them to perform this function.
Cardiac muscle cells are smaller than skeletal muscles, averaging 10–20 mm in diameter and 50–100 mm in length. However, they have large energy demands for continuous contraction and relaxation. This energy is almost exclusively derived from aerobic metabolism of energy reserves in...
Electrophysiology of Normal Cardiac Rhythm01:19

Electrophysiology of Normal Cardiac Rhythm

The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase of...
Mechanism of Cardiac Arrhythmias01:28

Mechanism of Cardiac Arrhythmias

Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.
The Electrical Double Layer01:30

The Electrical Double Layer

In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...
