Atypical Ophthalmic Presentation of First and Second Branchial Arch Developmental Anomaly
Delhi Journal of OphthalmologyFirst and second branchial arch anomalies encompass a group of congenital malformations that arise from defects in the embryological development of the branchial arches, structures critical to the formation of the head and neck.

Hemifacial microsomia: a literature review
Revista Facultad de Odontología Universidad de Antioquia, 2016 Hemifacial microsomia is the second congenital malformation in prevalence, after cleft lip and palate, and is described as a congenital alteration of the first and second branchial arches.

In ovo time-lapse analysis of chick hindbrain neural crest cell migration shows cell interactions during migration to the branchial arches [PDF]
, 2000 Hindbrain neural crest cells were labeled with DiI and followed in ovo using a new approach for long-term time-lapse confocal microscopy. In ovo imaging allowed us to visualize neural crest cell migration 2-3 times longer than in whole embryo explant ...

Clinical Experiences in the Surgical Treatment of Accessory Tragus [PDF]
Turkish Journal of Plastic Surgery, 2016 Objective: Tragus is a part of the external ear that develops from the first branchial arch. Accessory ear is a congenital external ear anomaly and has skin elevation containing remnant cartilage.

Cues from neuroepithelium and surface ectoderm maintain neural crest-free regions within cranial mesenchyme of the developing chick [PDF]
, 2002 Within the developing vertebrate head, neural crest cells (NCCs) migrate from the dorsal surface of the hindbrain into the mesenchyme adjacent to rhombomeres (r)1 plus r2, r4 and r6 in three segregated streams.

Graded potential of neural crest to form cornea, sensory neurons and cartilage along the rostrocaudal axis [PDF]
, 2004 Neural crest cells arising from different rostrocaudal axial levels form different sets of derivatives as diverse as ganglia, cartilage and cornea. These variations may be due to intrinsic properties of the cell populations, different environmental ...

Detailed expression profile of all six Glypicans and their modifying enzyme Notum during chick embryogenesis and their role in dorsal-ventral patterning of the neural tube [PDF]
, 2017 Vertebrate development is orchestrated by secreted signalling molecules that regulate cell behaviour and cell fate decisions during early embryogenesis.

Chick Lrrn2, a novel downstream effector of Hoxb1 and Shh, functions in the selective targeting of rhombomere 4 motor neurons [PDF]
, 2009 Background; Capricious is a Drosophila adhesion molecule that regulates specific targeting of a subset of motor neurons to their muscle target. We set out to identify whether one of its vertebrate homologues, Lrrn2, might play an analogous role in the ...

Dorsal hindbrain ablation results in rerouting of neural crest migration and changes in gene expression, but normal hyoid development [PDF]
, 1997 Our previous studies have shown that hindbrain neural tube cells can regulate to form neural crest cells for a limited time after neural fold removal (Scherson, T., Serbedzija, G., Fraser, S. E. and Bronner-Fraser, M. (1993).
