Diprosopus dirrhinus (nasal duplication) in a female Holstein Friesian calf: Clinical findings, diagnostic imaging and surgical management

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract An 11‐week‐old Holstein Friesian heifer calf presented with a congenital nasal abnormality characterised by an additional, turbinate‐like structure located dorsally on the nasal bridge. Clinical examination of the calf revealed normal respiratory function, with the accessory structure producing mucoid discharge from blind‐ended cavities ...

GPR37 Signaling Modulates Migration of Olfactory Ensheathing Cells and Gonadotropin Releasing Hormone Cells in Mice

Frontiers in Cellular Neuroscience, 2019
Gonadotropin releasing hormone (GnRH) neurons, part of the hypothalamic-pituitary-gonadal axis, regulate reproduction. Prenatally, GnRH neurons migrate into the brain from the nasal placode along terminal nerve fibers, intermixed with olfactory sensory ...

Latrophilin2 is involved in neural crest cell migration and placode patterning in Xenopus laevis

The International Journal of Developmental Biology, 2019
Latrophilin2 (Lphn2) is an adhesion-class of G protein-coupled receptor with an unknown function in development. Here, we show that Xenopus laevis lphn2 (Xlphn2) is involved in the migration and differentiation of neural crest (NC) cells and placode patterning in Xenopus laevis embryos. Although Xlphn2 mRNA was detected throughout embryogenesis, it was

Cryopreserved Human Otic Neuronal Spheroids Self‐assemble for Functional Connectivity Analysis and Long‐term Ototoxicity Evaluation

Advanced Science, Volume 13, Issue 7, 3 February 2026.
This study establishes a robust and reproducible protocol for generating human otic neuronal spheroids (hONS) from cryopreserved hPSC‐derived pre‐placodal ectoderm cells. These hONS further differentiate into functional SGN‐like neurons, which extend neurite projections toward both murine hair cells and human cortical organoids, thereby forming ...

The neural border: Induction, specification and maturation of the territory that generates neural crest cells.

Developmental Biology, 2018
The neural crest is induced at the edge between the neural plate and the nonneural ectoderm, in an area called the neural (plate) border, during gastrulation and neurulation.

Chicken HOXA3 Gene: Its Expression Pattern and Role in Branchial Nerve Precursor Cell Migration

International Journal of Biological Sciences, 2011
In vertebrates, the proximal and distal sensory ganglia of the branchial nerves are derived from neural crest cells (NCCs) and placodes, respectively.

Cortical Type: The Basis for a Modern Neurodevelopmental Synthesis (Ontogeny, Phylogeny, Synaptic Connectivity) of the Human Cerebral Cortex

Journal of Comparative Neurology, Volume 534, Issue 2, February 2026.
The parcellation of cortical types along the gradient of laminar complexity of the human cerebral cortex provides the basis for a Modern Neurodevelopmental Synthesis. This synthesis integrates ontogeny, phylogeny, gene expression, receptor architecture, cellular features, and synaptic connectivity and aims to guide experimental design for human ...

Pre‐oviposition development of the brown anole (Anolis sagrei)

Developmental Dynamics, Volume 255, Issue 2, Page 145-167, February 2026.
Abstract Background The brown anole, Anolis sagrei, has emerged as a representative squamate species for developmental studies during the past decades. Novel functional tools have been established to manipulate embryogenesis through genome editing or the introduction of small molecule inhibitors, and their effective use requires a thorough ...

Functional anterior pituitary generated in self-organizing culture of human embryonic stem cells

Nature Communications, 2016
Anterior pituitary is critical for endocrine systems. Its hormonal responses to positive and negative regulators are indispensable for homeostasis. For this reason, generating human anterior pituitary tissue that retains regulatory hormonal control in ...

Sensory cells in tunicates: insights into mechanoreceptor evolution

Frontiers in Cell and Developmental Biology
Tunicates, the sister group of vertebrates, offer a unique perspective for evolutionary developmental studies (Evo-Devo) due to their simple anatomical organization.
