eLife, 2022 The epiblast of vertebrate embryos is comprised of neural and non-neural ectoderm, with the border territory at their intersection harboring neural crest and cranial placode progenitors.

Frontiers in Cell and Developmental Biology, 2020 In vertebrates, Gonadotropin releasing hormone-1 (GnRH) neuroendocrine cells originate in the olfactory placode and migrate into the forebrain where they regulate reproduction.

Cell-autonomous involvement ofMab21l1is essential for lens placode development [PDF]
Development, 2003 The mab-21 gene was first identified because of its requirement for ray identity specification in Caenorhabditis elegans. It is now known to constitute a family of genes that are highly conserved from vertebrates to invertebrates, and two homologs, Mab21l1 andMab21l2, have been identified in many species. We describe the generation of Mab21l1-deficient

FGF signaling is essential for ophthalmic trigeminal placode cell delamination and differentiation [PDF]
Developmental Dynamics, 2009 AbstractThe ophthalmic trigeminal (opV) placode gives rise exclusively to sensory neurons of the peripheral nervous system, providing an advantageous model for understanding neurogenesis. The signaling pathways governing opV placode development have only recently begun to be elucidated.

Differentiation; research in biological diversity, 2019 The terminal nerve ganglion (TNG) is a well-known structure of the peripheral nervous system in cartilaginous and teleost fishes. It derives from the olfactory placode during embryonic development.

PACAP protects against TNFα-induced cell death in olfactory epithelium and olfactory placodal cell lines [PDF]
Molecular and Cellular Neuroscience, 2010 In mouse olfactory epithelium (OE), pituitary adenylate cyclase-activating peptide (PACAP) protects against axotomy-induced apoptosis. We used mouse OE to determine whether PACAP protects neurons during exposure to the inflammatory cytokine TNFα. Live slices of neonatal mouse OE were treated with 40 ng/ml TNFα ± 40nM PACAP for 6h and dying cells were ...

Cranial nerve development requires co-ordinated Shh and canonical Wnt signaling. [PDF]
PLoS ONE, 2015 Cranial nerves govern sensory and motor information exchange between the brain and tissues of the head and neck. The cranial nerves are derived from two specialized populations of cells, cranial neural crest cells and ectodermal placode cells. Defects in

The evolutionary history of vertebrate cranial placodes – I: Cell type evolution
Developmental Biology, 2014 Vertebrate cranial placodes are crucial contributors to the vertebrate cranial sensory apparatus. Their evolutionary origin has attracted much attention from evolutionary and developmental biologists, yielding speculation and hypotheses concerning their putative homologues in other lineages and the developmental and genetic innovations that might have ...

BMC Neuroscience, 2011 Background The vertebrate peripheral nervous system contains sensory neurons that arise from ectodermal placodes. Placodal cells ingress to move inside the head to form sensory neurons of the cranial ganglia.
