Cellular interplay in brain organoids: Connecting cell-autonomous and non-cell-autonomous mechanisms in neurodevelopmental disease.

The field of brain organoids has experienced a period of rapid and transformative growth, enabling researchers to investigate complex human biological mechanisms that were previously deemed intractable. This review provides an overview of the current landscape of brain organoids, with a particular focus on their relevance in the context of neurodevelopmental disorders. It also emphasizes the crucial role these models play in elucidating both cell-autonomous and non-cell-autonomous mechanisms. We describe how these two mechanisms, often considered to be independent, are intricately interconnected. In conclusion, this review aims to highlight how the utilization of brain organoids has considerably advanced our comprehension of neurodevelopmental disorders, while also delineating prospective avenues for investigating these complex conditions.
