Exploring landscapes of brain morphogenesis with organoids

Area of Science:

• Developmental Neuroscience
• Stem Cell Biology
• Neurobiology

Background:

• Organogenesis in vitro, particularly via organoid preparations, is revolutionizing developmental neuroscience.
• These methods provide unprecedented access to early human brain development and neural identity.
• Existing in vitro approaches, while powerful, present limitations when compared to in vivo development.

Purpose of the Study:

• To summarize key themes from a workshop on advancing in vitro neural differentiation.
• To highlight the limitations and potential of current brain organoid technology.
• To discuss the application of organoids in understanding healthy and diseased brains and cellular behaviors.

Main Methods:

• Review and synthesis of discussions from 'Thinking beyond the dish' workshop.
• Analysis of current organoid methodologies in developmental neuroscience.
• Comparative assessment of in vitro organoid development versus in vivo brain development.

Main Results:

• Organoid models recapitulate many aspects of early brain development with high fidelity.
• Significant differences persist between in vitro organoid development and in vivo brain development.
• Organoids show promise for studying neural disorders and exploring novel cellular behaviors.

Conclusions:

• Brain organoids are a valuable tool for studying human brain development and disease.
• Addressing the limitations of current organoid models is crucial for future advancements.
• Organoid technology holds significant potential for expanding our understanding of neuroscience.
