Human nervous system is arguably the most complex but highly organized organ. Foundation of its complexity and organization is laid down during regional patterning of neural tube (NT), the embryonic precursor to human nervous system. Historically, studies of NT patterning have relied on animal models to uncover underlying principles. Recently, human pluripotent stem cell (hPSC)-based models of neurodevelopment, including neural organoids1-5 and bioengineered NT development models6-10, are emerging. However, existing hPSC-based models fail to recapitulate neural patterning along both rostral-caudal (R-C) and dorsal-ventral (D-V) axes in a three-dimensional (3D) tubular geometry, a hallmark of NT development...
