Quantifying differentiation of progenitor populations using cerebral organoid models for neurodevelopmental disorders

Abstract

Summary: Neurodevelopmental disorders are characterized by complex phenotypes that often result from concomitant dysregulation of cell proliferation, differentiation, or other crucial developmental processes. Here, we present a protocol to quantify differentiation of progenitor populations during early stages of neurogenesis in induced pluripotent stem cell (iPSC)-derived cerebral organoids. We describe steps for organoid differentiation and maturation, sample preparation, immunofluorescence, and imaging and analysis using epifluorescence microscopy. This protocol can be used to compare cerebral organoids from control and patient-derived iPSCs.For complete details on the use and execution of this protocol, please refer to Rakotomamonjy et al. (2023).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
