regulates regulation of epithelial to mesenchymal transition neural crest formation regulation of anatomical structure morphogenesis biological regulation regulation of neural crest formation biological_process tb GO:0090299 2010-03-12T04:08:26Z Any process that modulates the rate, frequency, or extent of neural crest formation. Neural crest formation is the formation of the specialized region of ectoderm between the neural ectoderm (neural plate) and non-neural ectoderm. The neural crest gives rise to the neural crest cells that migrate away from this region as neural tube formation proceeds.
