Modeling Alzheimer's disease using human cell derived brain organoids and 3D models

Area of Science:

• Neuroscience
• Stem Cell Biology
• Pathology

Background:

• Age-related neurodegenerative diseases, such as Alzheimer's disease (AD), present significant challenges due to a lack of cures and limited treatments.
• A scarcity of functional, human-derived brain tissues with diverse genetic backgrounds and cellular subtypes hinders sporadic AD (sAD) research.
• Human stem cell-derived brain organoids show potential in modeling human brain cytoarchitecture and AD-like pathology.

Purpose of the Study:

• To review current strategies for utilizing brain organoids in Alzheimer's disease research.
• To discuss the challenges of using organoid models for studying age-related brain diseases.

Main Methods:

• Review of existing literature on brain organoid applications in AD research.
• Analysis of the capabilities and limitations of organoid models for neurodegenerative disease studies.

Main Results:

• Brain organoids can recapitulate aspects of human brain development and AD pathology.
• Organoids provide a valuable tool for investigating the link between AD pathology and neural cell dysfunction.
• Challenges remain in fully replicating the complexity of the aging human brain and sAD in organoid systems.

Conclusions:

• Brain organoids are an emerging and valuable tool for advancing Alzheimer's disease research.
• Further development is needed to overcome challenges in modeling complex age-related neurological disorders.
