🧬 Research Spotlight at Cardiology & Cardiovascular Science 2026
Researcher: Shion Nagasawa
Institution: Chiba University, Japan
Presentation Format: Poster Presentation (In-Person)
Scientific Event: International Conference on Cardiology and Cardiovascular Science
Dates: March 26–28, 2026
Mode: Hybrid (Singapore & Online)
🫀 Study Title
Single Cell Analysis of Endothelial Cells in Male and Female Developing Hearts
🔍 What Makes This Study Unique
Investigates sex-based differences in the cardiovascular system before birth
Challenges the belief that cardiac sex differences arise only after hormonal influence
Focuses on endothelial cells, key regulators of vascular structure and function
Applies single-cell RNA sequencing to reveal cellular and molecular diversity
🧪 Research Approach in Brief
Embryonic mouse hearts analyzed at E17.5 and E12.5 developmental stages
Cardiac endothelial cells isolated using fluorescence-activated cell sorting (FACS)
Male and female cells distinguished within the same dataset using cell-multiplexing oligos
Public datasets leveraged to validate sex-specific gene expression patterns
📊 Key Findings at a Glance
Identification of endothelial subtypes:
Arterial
Two capillary populations
Venous endothelial cells
Female embryos showed a higher proportion of arterial endothelial cells
Male endothelial cells demonstrated increased expression of cell motility–related genes
Female endothelial cells showed enhanced pathways related to:
Endothelial differentiation
Response to laminar fluid shear stress
Similar gene expression profiles observed at earlier stages, suggesting early onset of sex differences
🧠 Scientific Significance
Reveals that cardiac vascular sex differences are programmed during embryogenesis
Provides mechanistic insight into future sex-specific cardiovascular function and disease risk
Supports the need for sex-aware approaches in cardiovascular research
Strengthens the role of single-cell technologies in developmental biology
👩🔬 Researcher Profile
PhD candidate focused on heart development and cardiovascular disease mechanisms
