Schematic of three neural organogenesis approaches in vitro. (a) Stepwise, direct organization of region-specific or population-enriched organoids; (b) assemble and direct distinct organ-specific progenitor cells or stem cells to form specific morphogenesis organ; (c) assemble embryoid bodies for induction of multilayer organoids.
