The generation of human pluripotent stem cell (hPSC)-derived brain organoids is continuously refined, enhancing their reproducibility and complexity. Here, we present a guided differentiation protocol for generating cortical forebrain organoids and cortico-pericyte (CP)assembloids composed of a robust outer radial glia (oRG) population and an expanded outer subventricular zone (oSVZ). We describe the steps to generate hPSC-derived cortical organoids (COs), cortical pericytes, and CP assembloids. Moreover, we outline the procedures to characterize the organoids by immunostaining and to perform single-cell dissociation. For complete details on the use and execution of this protocol, please refer to Walsh et al.1.
