Here, we demonstrate self-organized formation of apico-basally polarized cortical tissues from ESCs using an efficient three-dimensional aggregation culture (SFEBq culture). The generated cortical neurons are functional, transplantable, and capable of forming proper long-range connections in vivo and in vitro. The regional identity of the generated pallial(More)
Balanced organogenesis requires the orchestration of multiple cellular interactions to create the collective cell behaviours that progressively shape developing tissues. It is currently unclear how individual, localized parts are able to coordinate with each other to develop a whole organ shape. Here we report the dynamic, autonomous formation of the optic(More)
Embryonic stem (ES) cells differentiate into neuroectodermal progenitors when cultured as floating aggregates in serum-free conditions. Here, we show that strict removal of exogenous patterning factors during early differentiation steps induces efficient generation of rostral hypothalamic-like progenitors (Rax(+)/Six3(+)/Vax1(+)) in mouse ES cell-derived(More)
Differentiation of CNS glia is regulated by Notch signaling through neuron-glia interaction. Here, we identified Delta/Notch-like EGF-related receptor (DNER), a neuron-specific transmembrane protein, as a previously unknown ligand of Notch during cellular morphogenesis of Bergmann glia in the mouse cerebellum. DNER binds to Notch1 at cell-cell contacts and(More)
During early telencephalic development, the major portion of the ventral telencephalic (subpallial) region becomes subdivided into three regions, the lateral (LGE), medial (MGE), and caudal (CGE) ganglionic eminences. In this study, we systematically recapitulated subpallial patterning in mouse embryonic stem cell (ESC) cultures and investigated temporal(More)
Here, using further optimized 3D culture that allows highly selective induction and long-term growth of human ES cell (hESC)-derived cortical neuroepithelium, we demonstrate unique aspects of self-organization in human neocorticogenesis. Self-organized cortical tissue spontaneously forms a polarity along the dorsocaudal-ventrorostral axis and undergoes(More)
In the mammalian cortex, the dorsal telencephalon exhibits a characteristic stratified structure. We previously reported that three-dimensional (3D) culture of mouse ES cells (mESCs) can efficiently generate cortical neuroepithelium (NE) and layer-specific cortical neurons. However, the cortical NE generated in this mESC culture was structurally unstable(More)
We have identified a novel epidermal growth factor (EGF)-like repeat-containing single-pass transmembrane protein that is specifically expressed in the developing and mature central nervous system. Sequence analysis revealed that the 10 EGF-like repeats in the extracellular domain are closely related to those of the developmentally important receptor Notch(More)
In vitro neural differentiation culture of embryonic stem cells (ESCs) provides a promising tool for preparing neural cells for replacement therapies and a versatile system for understanding mechanisms of neurogenesis. Consistent with the neural-default model, neural differentiation spontaneously occurs in ESCs cultured in medium containing minimal(More)
During lamination of the cerebellar cortex, granule cells initially migrate tangentially along the external granule layer, and then make a vertical turn and migrate radially to the internal granule layer. We comparatively analyzed the properties of biphasic migration of granule cells in a microexplant culture in which quantitation of morphology and(More)
