Brain organoids for hypoxic-ischemic studies: from bench to bedside

Area of Science:

• Neuroscience
• Developmental Biology
• Pathophysiology

Background:

• Current human brain development research relies heavily on animal models, which have limitations due to species-specific differences in maturation.
• In vivo animal studies may not fully replicate the complexities of human brain development and disease progression.
• There is a critical need for complementary models to enhance the translatability of preclinical findings to human clinical trials.

Approach:

• This review highlights the use of three-dimensional (3D) human brain organoid cultures as a complementary tool to in vivo animal models.
• Focuses on developing a human brain organoid model for studying hypoxic-ischemic (HI) brain injury.
• Explores the potential of organoids to bridge the gap between animal experiments and human pathophysiology.

Key Points:

• Human brain organoids provide a more accurate model for studying human brain development and disease compared to traditional animal models.
• Organoid technology can enhance the translatability of preclinical research, leading to more effective human trials.
• This approach allows for the investigation of fundamental aspects of hypoxic-ischemic brain injury pathophysiology.
• The model offers opportunities to explore sex-based differences in HI brain injury responses.

Conclusions:

• Human brain organoids represent a significant advancement in modeling human brain development and injury.
• Utilizing brain organoids can improve the predictive value of preclinical studies for human neurological disorders.
• Further research with brain organoids holds promise for uncovering novel therapeutic strategies for hypoxic-ischemic brain injury.
