Establishment of In Vitro Brain Models for AON Delivery.

Progress in stem cell biology has made it possible to generate human-induced pluripotent stem cells (hiPSC) that can be differentiated into complex, three-dimensional structures, where the cells are spatially organized. To study brain development, Lancaster and colleagues developed an hiPSC-derived three-dimensional organoid culture system, termed cerebral organoids, that develop various discrete, although interdependent, brain regions. Here we describe in detail the generation of cerebral organoids using a modified version of the culture protocol.
