Human stem cell models to study placode development, function and pathology
Development, 2022 ABSTRACT Placodes are embryonic structures originating from the rostral ectoderm that give rise to highly diverse organs and tissues, comprising the anterior pituitary gland, paired sense organs and cranial sensory ganglia. Their development, including the underlying gene regulatory networks and signalling pathways, have been for the ...

A Molecular Analysis of Neural Olfactory Placode Differentiation in Human Pluripotent Stem Cells
Stem Cells and Development, 2022 During embryonic development, the olfactory sensory neurons (OSNs) and the gonadotropic-releasing hormone neurons (GNRHNs) migrate from the early nasal cavity, known as the olfactory placode, to the brain. Defects in the development of OSNs and GNRHNs result in neurodevelopmental disorders such as anosmia and congenital hypogonadotropic hypogonadism ...

In adult rodents, the peptide galanin is expressed in a subpopulation of hypothalamic luteinizing hormone‐releasing hormone (LHRH) neurones in an activity‐dependent manner. In this investigation, we examined whether galanin mRNA expression in mice was activated coincident with LHRH mRNA expression, as LHRH neurones differentiate from the olfactory ...

Neural Crest‐Placode Cell Interactions during Cranial Ganglia Assembly
The FASEB Journal, 2016 The cranial sensory ganglia are created from two motile cell populations, neural crest cells and placode cell‐derived neurons. Defects in the migration and interaction of these cells can cause abnormalities in craniofacial development and in the formation of the sensory nervous system, leading to conditions such as cleft lip/palate, neuralgia, and ...

Cell migration from the transplanted olfactory placode in Xenopus
Anatomy and Embryology, 1995The eye vesicle of Xenopus borealis has been replaced with the transplanted olfactory primordium from Xenopus laevis in an attempt to determine whether cells from the transplant could migrate along the regrowing olfactory nerve and become incorporated into the CNS of the host. The use of X. laevis and X.

Hair cells in ascidians and the evolution of lateral line placodes
Evolution & Development, 2004The vertebrate hair cells are ciliary highly differentiated mechanoreceptors whose name derives from the peculiar microvilli, called stereovilli, that protrude into the fluid-filled cavities of the inner ear or lateral line organs. They differ from the primary sensory cells found in most invertebrates in that they are axonless, thus being secondary ...

Neural crest and placode roles in formation and patterning of cranial sensory ganglia in lamprey
Genesis, 2020Vertebrates possess paired cranial sensory ganglia derived from two embryonic cell populations, neural crest and placodes. Cranial sensory ganglia arose prior to the divergence of jawed and jawless vertebrates, but the developmental mechanisms that ...

Abstract During embryonic development, 2 populations of multipotent stem cells, cranial neural crest cells (NCCs) and epibranchial placode cells (PCs), are anatomically adjacent to each other. The coordinated migration of NCCs and PCs plays a major role in the morphogenesis of craniofacial skeletons and cranial nerves.
