Sex-Based Mechanisms of Cardiac Development and Function: Applications for Induced-Pluripotent Stem Cell...

Area of Science:

• Cardiovascular Science
• Developmental Biology
• Genetics

Background:

• Males and females have inherent differences in heart structure and function.
• Cardiovascular disease prevalence and severity differ between sexes, but underlying mechanisms remain unclear.
• Sex chromosomes and hormones are primary drivers of cardiac sex dimorphism.

Purpose of the Study:

• To provide an overview of the roles of sex chromosomes and hormones in cardiac development.
• To explore sex hormone signaling pathways in the heart.
• To discuss how stem cell models and multi-omic approaches advance the understanding of cardiac sex differences.

Main Methods:

• Review of current literature on sex-based cardiac dimorphism.
• Analysis of induced pluripotent stem cell-derived cardiac models.
• Application of multi-omic approaches, including single-cell RNA sequencing.

Main Results:

• Sex chromosomes and hormones significantly influence cardiac physiology and pathophysiology.
• Stem cell-derived cardiac models offer insights into sex-specific cellular and molecular mechanisms.
• Multi-omic data reveal novel sex-specific gene expression patterns in the heart.

Conclusions:

• Understanding cardiac sex differences is crucial for personalized cardiovascular medicine.
• Stem cell-based models and advanced sequencing technologies are powerful tools for investigating sex-specific heart development and disease.
• Further research is needed to fully elucidate the complex interplay of genetic and hormonal factors in cardiac dimorphism.
