The new work, conducted in the Waisman Center laboratory of UW-Madison neuroscientist Su-Chun Zhang, reveals the pervasive influence of Pax6 on the neuroectoderm, a structure that arises early in embryonic development and that churns out the two primary forms of brain cells - neurons and glial cells - and the hundreds of cell subtypes that make up the human brain.
In addition, we have included in our study inhibitor of DNA binding genes ID1, ID2, and ID3 (inhibitors of DNA binding 1,2, and 3, dominant negative helix-loop-helix protein), the expression of which is known to inhibit neuroectoderm differentiation in undifferentiated mouse ESCs (14), although the importance of the ID genes in hESCs has yet to be confirmed.
The Drosophila short gastrulation gene prevents Dpp from autoactivating and suppressing neurogenesis in the neuroectoderm.

Merkel cells are derived from the neuroectoderm and function as type I mechanoreceptors by forming synapselike contacts with the tactile hair discs of Pinkus.
8 In the present case, no neurofibroma was found anterior to C2, and since it is a widely accepted fact that in neurofibromatosis there is genetically related maldevelopment of neuroectoderm and mesoderm, there may be associated deformities in the adjacent structures and ligaments--in turn leading to AAD.
Ninety percent of reported nasal gliomas do not contain neurons, possibly because of the low levels of oxygen in the mass and the lack of differentiation from embryonic neuroectoderm.
Several cutaneous lesions that may potentially be confused with neoplasms include selected proliferations of the adnexae, mesenchymal dermal elements, "rests" or remnants of the neuroectoderm, and inflammatory conditions.
Meningiomas arise from meningothelial arachnoid cells, which are derived from the neuroectoderm.
The endolymphatic sac, located between the dura and the posterior surface of the petrous portion of the temporal bone, originates in the neuroectoderm and is lined with both columnar and simple cuboidal epithelium.
