This review summarizes the current understanding of the development of the neuroendocrine gonadotropin-releasing hormone (GnRH) system, including discussion on open questions regarding (1) transcriptional regulation of the Gnrh1 gene; (2) prenatal development of the GnRH1 system in rodents and humans; and (3) paracrine and synaptic communication during migration of the GnRH cells.
Keywords: GnRH; development; guidance cues; migratory pathway; olfactory ensheathing cells; olfactory placode; synaptic and paracrine signals; terminal nerve; transcription factors.
