Animal Disease Models and Patient-iPS-Cell-Derived In Vitro Disease Models for Cardiovascular Biology-How Close to...

Area of Science:

• Cardiovascular research
• Translational medicine
• Disease modeling

Background:

• Traditional animal models (zebrafish, rodents, canines, pigs) offer physiological similarities but face handling, welfare, and species-specific limitations.
• Differences in disease mechanisms and organ characteristics between species and humans necessitate improved preclinical models.
• Existing preclinical studies rely on animal models for drug safety and efficacy evaluation due to a lack of alternatives.

Purpose of the Study:

• To review and explore the utility of various disease models in cardiovascular research.
• To evaluate the potential of induced pluripotent stem cell (iPSC)-derived in vitro models and humanized animals.
• To discuss the challenges and integration of machine learning in disease modeling.

Main Methods:

• Review of current animal disease models in cardiovascular research.
• Exploration of induced pluripotent stem cell (iPSC)-derived in vitro models, including 3D culture systems.
• Discussion of humanized animal models and machine learning applications.
• Comparative analysis of disease mechanisms across species and human relevance.

Main Results:

• Animal models, while valuable, present significant challenges in translation to human physiology.
• iPSC-derived human cardiomyocytes offer a genetically identical in vitro model.
• Humanized animals and advanced in vitro systems show promise for better disease mimicry.
• Machine learning presents new avenues for refining disease models.

Conclusions:

• A multi-modal approach integrating animal models, iPSC technology, humanized animals, and machine learning is essential.
• Combining these diverse modeling strategies can bridge the gap between preclinical data and human disease.
• Future research should focus on synergistic application of these methods to enhance the accuracy and translatability of disease models.
