Contributions of placodal and neural crest cells to avian cranial peripheral ganglia
American Journal of Anatomy, 1983AbstractThe method of embryonic tissue transplantation was used to confirm the dual origin of avian cranial sensory ganglia, to map precise locations of the anlagen of these sensory neurons, and to identify placodal and neural crest‐derived neurons within ganglia.

Neural Crest and Placodal Cells Contributions to Cranial Sensory Development
2022The sensory system of vertebrates is incredibly complex. Many important components of the sensory system are located within the cranial region, including the sense organs and cranial sensory ganglia. Early in development two progenitor populations, the neural crest and the cranial placodes, arise at the neural plate border and throughout vertebrate ...

Cell Migration from the Olfactory Placode and the Ontogeny of the Neuroendocrine Compartments
Zoological Science, 1995The olfactory placode and its derivative, the olfactory pit, give rise to several different populations of migrating cells, which contribute to drive the organization of the prosencephalon, but also to form a part of the central neuroendocrine compartments.

Cell migration from the chick olfactory placode: a light and electron microscopic study
Development, 1982ABSTRACT The differentiation of the olfactory placode in the chick has been studied using light and electron microscopy. Special attention was paid to the appearance of neuronal cells within the placodal ectodermal thickening, the migration of cells out of this tissue and the appearance of the first fila olfactoria in the differentiating

Primary Cell Culture of LHRH Neurones from Embryonic Olfactory Placode in the Sheep (Ovis aries)
Journal of Neuroendocrinology, 1997The aim of this study was to establish an in vitro model of ovine luteinizing hormone‐releasing hormone (LHRH) neurones. Olfactory placodes from 26 day‐old sheep embryos (E26) were used for explant culture. Cultures were maintained successfully up to 35 days, but were usually used at 17 days for immunocytochemistry.

The recent production of a monoclonal antibody (NC-1) recognizing migrating avian neural crest (NC) cells (M. Vincent, J. L. Duband , and J. P. Thiery , Dev. Brain Res. 9, 235-238, 1983) allowed us to detail their migration pathways at the trunk level of the chick embryo. Three routes can be recognized: NC cells facing the bulk of the somite accumulate

To test extracellular signals that direct the development of the olfactory system, we have generated clonal temperature-sensitive cell lines that represent distinct cellular lineages derived from the E10 mouse olfactory placode. Two of these lines, OP6 and OP27, express (at the permissive temperature), a transcriptional profile representing ...

Cellular Reprogramming
ABSTRACTThe mammalian olfactory neuronal lineage is regenerative, and accordingly, maintains a population of pluripotent cells that replenish olfactory sensory neurons and other olfactory cell types during the life of the animal. Moreover, in response to acute injury, the early transit amplifying cells along the olfactory sensory neuronal lineage are ...

Cell proliferation in the embryonic quail uropygial gland during placode stage to lumen formation
Anatomy and Embryology, 1989The uropygial gland is one of the epidermal derivatives in birds. In the beginning of the morphogenesis of the uropygial gland of the quail embryo, placode formation occurs: Epidermal basal cells remain cuboidal until day 7 of incubation. At day 8 they begin to elongate, become columnar, and develop placode-like structure at day 9.

AbstractDapper (Dpr) proteins are context‐dependent regulators of Wnt and Tgfβ signaling. However, although inroads into their molecular properties have been made, their expression and biological function are not understood. Searching for avian Dpr genes, we found that the chicken harbors a Dpr1 and a Dpr2 paralogue only.
