Reaching into the toolbox: Stem cell models to study neuropsychiatric disorders

Area of Science:

• Neuroscience
• Genetics
• Stem Cell Biology

Background:

• Neuropsychiatric disorders, including autism spectrum disorder (ASD), major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia (SZ), are complex conditions.
• Their complexity arises from polygenic inheritance, intricate brain connectivity, and dysregulation of human-specific neurodevelopmental processes.
• Understanding these disorders requires advanced models that capture biochemical and cellular intricacies.

Purpose of the Study:

• To discuss the application of cutting-edge tools in modeling neuropsychiatric disorders.
• To highlight the development of novel cell-based 2D and 3D brain organoid models.
• To unravel the pathophysiology of complex mental illnesses.

Main Methods:

• Utilizing advanced genetic tools, including CRISPR-Cas9 gene editing technology.
• Developing and employing cell-based two-dimensional (2D) models.
• Creating and analyzing three-dimensional (3D) brain organoid models.

Main Results:

• Demonstrated the utility of CRISPR-Cas9 in creating sophisticated disease models.
• Established 2D and 3D models that better recapitulate the human brain's complexity.
• These models offer improved platforms for studying neuropsychiatric disorder mechanisms.

Conclusions:

• Advanced tools and modeling techniques are crucial for understanding neuropsychiatric disorders.
• Cell-based 2D and 3D brain organoid models provide powerful systems for research.
• These models facilitate deeper insights into the pathophysiology of complex brain conditions.
