Bridging population and cell: modelling complex diseases with human induced pluripotent stem cells

Area of Science:

• Biomedical Research
• Stem Cell Biology
• Genetics

Background:

• Induced pluripotent stem cells (iPSCs) are valuable for studying patient-specific diseases.
• Traditionally used for monogenic diseases, iPSCs are now being explored for complex diseases.
• Scalability advances enable large-scale iPSC studies for complex genotype-phenotype relationships.

Purpose of the Study:

• To review the challenges and opportunities of using iPSCs for complex disease modeling.
• To highlight key themes in advancing iPSC technology for complex disease research.
• To discuss strategies for improving reliability and translational relevance of iPSC-based studies.

Main Methods:

• Review of current literature on iPSC technology and complex disease modeling.
• Structured analysis around detecting subtle genetic effects.
• Exploration of methods for modeling environmental context and expanding genetic diversity.

Main Results:

• iPSCs present significant potential for modeling complex diseases at scale.
• Key challenges include detecting small genetic effects and incorporating environmental influences.
• Expanding genetic diversity in iPSC models is crucial for broader applicability.

Conclusions:

• Addressing limitations in iPSC technology is essential for advancing complex disease research.
• Future directions involve enhancing subtle effect detection, environmental modeling, and genetic diversity.
• Optimized iPSC models hold promise for improving translational relevance in complex disease studies.
