Toxicity assessment using neural organoids: innovative approaches and challenges.

Abstract

Assessment of toxicity and efficacy in the nervous system is essential to ensure the safety of compounds and the efficacy of neurotherapeutics. Recently, technologies using neural organoids to mimic the structural and functional properties of human brain tissue have been developed to improve our understanding of human-specific brain development and to model neurodevelopmental disorders. This approach offers the potential for standardized toxicity testing and large-scale drug screening at the organ level. Here, we review recent advances in neural organoids and explore the possibility of establishing more accurate and efficient systems for toxicological screening applications. Our review provides insights into toxicity and efficacy assessment research using neural organoids.
