Integrating population genetics, stem cell biology and cellular genomics to study complex human diseases

Area of Science:

• Stem cell biology
• Population genetics
• Cellular genomics

Background:

• Human pluripotent stem (hPS) cells are versatile models for in vitro human biology.
• Technological advances enable large-scale hPS cell studies to investigate genetic regulation of phenotypes.
• Integrating hPS cells with single-cell sequencing allows identification of context-dependent genetic effects.

Purpose of the Study:

• To discuss how integrating stem cell biology, population genetics, and cellular genomics can elucidate the functional consequences of human genetic variation.
• To examine challenges in cost-effectively and practically scaling these integrated approaches.
• To highlight key areas benefiting from population-scale hPS cell studies.

Main Methods:

• Leveraging human pluripotent stem cells for in vitro modeling.
• Employing single-cell sequencing for high-resolution genetic effect analysis.
• Integrating population genetics and cellular genomics data.

Main Results:

• Population-scale hPS cell studies can resolve functional consequences of human genetic variation.
• These studies can elucidate mechanisms underlying complex disease risk loci.
• They enable evaluation of relationships between common genetic variation and pharmacotherapeutic phenotypes.

Conclusions:

• The convergence of stem cell biology, population genetics, and cellular genomics is crucial for understanding human genetic variation.
• Addressing challenges in scaling these integrated approaches is essential for progress.
