Abstract
This protocol generates 3D cerebral organoids from human embryonic stem cells (hESCs) and patient-derived induced pluripotent stem cells (iPSCs) to model early cortical development and investigate schizophrenia-related developmental abnormalities. Organoids recapitulate the first trimester of human brain development, revealing disrupted neural progenitor cell migration, reduced cortical neuronal maturation, and altered FGFR1 signaling in schizophrenia models, with implications for understanding early pathogenic mechanisms in psychiatric disease.
