Schizophrenia Brain Organoids
Source Stachowiak et al.
Abstract
This protocol describes the generation of cerebral organoids from human embryonic stem cells (H9, HUES8) and induced pluripotent stem cells to model early cortical development and investigate maldevelopment associated with schizophrenia. The protocol includes neural induction, organoid formation, immunocytochemical analysis, and computational morphological assessment of proliferation and neuronal organization.
