Modeling Cardiac SARS-CoV-2 Infection with Human Pluripotent Stem Cells

Area of Science:

• Cardiology
• Virology
• Stem Cell Biology

Background:

• The COVID-19 pandemic, caused by SARS-CoV-2, has systemic effects beyond the respiratory tract.
• Cardiac damage has been reported in COVID-19 patients, suggesting direct viral impact on the heart.

Purpose of the Study:

• To review studies using human pluripotent stem cells (hPSCs) to investigate SARS-CoV-2 cardiac tropism and effects.
• To explore potential therapeutic interventions for SARS-CoV-2-induced cardiac damage.

Main Methods:

• Utilizing hPSC-derived cardiovascular cell types to model SARS-CoV-2 infection in vitro.
• Analyzing viral tropism, cellular effects, and potential therapeutic targets in human cardiac models.

Main Results:

• SARS-CoV-2 infects and replicates in hPSC-derived cardiomyocytes and sinoatrial nodal cells.
• Significant viral effects observed on cardiomyocyte structure, gene expression, and survival.
• Non-parenchymal cardiac cells show less susceptibility to infection.

Conclusions:

• hPSC-derived cardiac models are effective for studying SARS-CoV-2 cardiac impact.
• These models offer insights into mechanisms of cardiac injury and potential therapeutic strategies.
