Cerebral organoids are three-dimensional, in vitro cultured brains that mimic the activities of the human brain. They have emerged as invaluable tools to comprehend evolution, disease pathogenesis, and neurodevelopmental processes. However, the development of these organoids is still in nascent stages with several limitations that hinder their broad applications. A major obstacle is the absence of a functional vasculature that can restrict the size of organoids, trigger cell death, and prevent cell differentiation in the organoids.
