The floor plate (FP) is a critical signaling center during neural development located along the ventral midline of the embryo. Little is known about human FP development due the lack of tissue accessibility. Here we report the efficient derivation of human embryonic stem cells (hESC−) derived FP tissue capable of secreting Netrin-1 and SHH and patterning primary and hESC derived tissues. FP induction in hESCs is dependent on early SHH exposure and occurs at the expense of anterior neurectoderm (AN). Global gene expression and functional studies identify SHH-mediated inhibition of DKK-1 as key factor in FP versus AN specification. hESC derived FP tissue is shown to be of anterior SIX6+ character but responsive to caudalizing factors suppressing SIX6 expression and inducing a shift in usage of region-specific SHH enhancers. These data define the early signals that drive human FP versus AN specification and determine regional identity in hESC derived FP.
