Three-dimensional spheroid models for cardiovascular biology and pathology

Area of Science:

• Biomedical Engineering
• Cell Biology
• Cardiovascular Research

Background:

• Traditional two-dimensional (2D) cell cultures inadequately mimic complex tissue microenvironments.
• Scaffold-free three-dimensional (3D) cellular spheroids provide more intricate cell-cell and cell-extracellular matrix (ECM) interactions, closely resembling *in vivo* conditions.

Purpose of the Study:

• To review the advantages and limitations of 3D spheroid models in cardiovascular research.
• To discuss their applications in studying angiogenesis, cardiovascular pathobiology, drug development, and cardiac tissue repair.

Main Methods:

• Literature review of existing studies on 3D spheroid models in cardiovascular research.
• Analysis of the benefits and drawbacks of using 3D spheroids for *in vitro* modeling.

Main Results:

• 3D spheroids offer enhanced recapitulation of *in vivo* cardiovascular microenvironments.
• They show significant potential for advancing the study of angiogenesis and cardiovascular disease.
• Applications in cardiac drug development and tissue repair are promising but require further exploration.

Conclusions:

• 3D spheroid models represent a significant advancement over 2D cultures for cardiovascular research.
• Further research is needed to fully realize the experimental potential of 3D spheroids in understanding and treating cardiovascular diseases.
• These models hold promise for improving drug efficacy and developing novel cardiac tissue repair strategies.
