iPSC models of mitochondrial diseases

Area of Science:

• Biomedical Research
• Stem Cell Biology
• Mitochondrial Medicine

Background:

• Mitochondrial diseases cause multi-systemic defects, often affecting critical organs like the brain and heart.
• Studying these diseases is challenging due to difficult-to-access tissues and limitations in mitochondrial DNA (mtDNA) engineering.
• Most mitochondrial diseases currently lack effective treatments.

Purpose of the Study:

• To review the application of human induced pluripotent stem cells (iPSCs) in modeling mitochondrial diseases.
• To explore how iPSC-derived 2D cells and 3D organoids are used to study nuclear and mtDNA defects.
• To highlight the potential of iPSC models for therapeutic development and toxicity assessment.

Main Methods:

• Review of existing literature on iPSC applications for mitochondrial disease research.
• Analysis of studies utilizing 2D cell cultures derived from iPSCs.
• Examination of research employing 3D organoid models derived from iPSCs.

Main Results:

• iPSCs provide patient- and tissue-specific human model systems for studying mitochondrial diseases.
• iPSC-derived models enable dissection of mutation-specific defects and assessment of treatment impacts.
• Both 2D and 3D iPSC-derived models are valuable tools for investigating nuclear and mtDNA-related mitochondrial disorders.

Conclusions:

• iPSC technology is crucial for advancing the study of complex mitochondrial diseases.
• The use of iPSC-derived models is expanding, promising innovative platforms for drug discovery and toxicity testing.
• This field holds significant potential for developing treatments for debilitating mitochondrial disorders with unmet medical needs.
