Reviewing vascular influences on neuronal migration, cortical development, and neurodevelopmental disorders: focus on autism, ADHD and schizophrenia

During cortical development, newly born neurons migrate radially or tangentially from their origin to expand the cortex. Simultaneously, neuron-derived factors support angiogenesis, and an elaborate network of blood cerebral vessels develops in the cortex. Traditionally, blood cerebral vessels were considered to support the growing cortex or migrating neurons by providing nutrients and oxygen. However, recent studies have shed light on Endothelial cells' influence on cortical development; they guide neuronal migration by providing molecular cues and structural support. Here, we review the current understanding of how CNS cerebral vessels support neurogenesis, neuronal migration, and the formation of the six-layer cortical structure during development. Additionally, we explore current knowledge regarding the vascular role in neurodevelopmental disorders, including autism spectrum disorder, attention deficit hyperactivity disorder, and schizophrenia.
