Organoid technologies meet genome engineering.

Area of Science:

• Biomedical Research
• Developmental Biology
• Stem Cell Biology

Background:

• Three-dimensional (3D) stem cell differentiation cultures, specifically organoids, are emerging as powerful in vitro models.
• Organoids mimic in vivo organ structure and function, complementing traditional 2D cultures and animal models.
• Accurate modeling of development and disease in organoids requires genomic modification capabilities.

Purpose of the Study:

• To review the historical development and current applications of genome engineering in 3D organoid models.
• To discuss the technical considerations for implementing genome engineering in organoids.
• To explore the future potential of combining genome engineering with organoid technology for biomedical research.

Main Methods:

• Review of existing literature on 3D organoid models and genome engineering technologies.
• Focus on CRISPR/Cas9 as a key tool for genetic modification in organoids.
• Discussion of methods for generating reporter cell lines and introducing disease mutations.

Main Results:

• Genome engineering, particularly CRISPR/Cas9, enables precise genetic modifications in organoid cells.
• These modifications facilitate the creation of reporter lines for lineage tracing and the introduction of disease mutations for modeling.
• Organoids with engineered genomes provide more faithful recapitulation of in vivo processes.

Conclusions:

• Genome engineering significantly advances the utility of 3D organoid models for studying human development and disease.
• CRISPR/Cas9 technology is pivotal for creating sophisticated organoid disease models and reporter lines.
• The integration of genome engineering and organoids holds substantial promise for future biomedical research and translational medicine.
