Differential distribution of the Ca (2+) regulator Pcp4 in the branchial arches is regulated by Hoxa2. [PDF]

PLoS ONE, 2013
Branchial arches are externally visible tissue bands in the head region of all vertebrate embryos. Although initially formed from similar components, each arch will give rise to different head and neck structures. In a screen designed to characterize the

The subfunctionalization of shox and shox2 paralogs in shark highlights both shared and distinct developmental mechanisms of branchial arches and fins [PDF]

Frontiers in Cell and Developmental Biology
The genomes of most gnathostomes contain two paralogs of the shox gene, shox and shox2, both of which are implicated in the development of two key morphological innovations: the jaw apparatus derived from the branchial arches and the paired appendages ...

High-throughput microRNA sequencing in the developing branchial arches suggests miR-92b-3p regulation of a cardiovascular gene network [PDF]

Frontiers in Genetics
Vertebrate branchial arches (BAs) are a developmental paradigm, undergoing coordinated differentiation and morphogenesis to form various adult derivative tissues. MicroRNAs can strengthen gene regulatory networks (GRNs) to promote developmental stability.

A potential role of Fgf3 for epibranchial formation in zebrafish [PDF]

Frontiers in Cell and Developmental Biology
In fish, epibranchials are dorsal facial skeletal elements composing the branchial basket, which articulate with ceratobranchials ventrally and pharyngobranchials dorsally. They form in the posterior pharyngeal arches through endochondral bone formation.

Third and Fourth Branchial Arch Anomalies in Children: Insights from a Tertiary Care Center

Journal of Indian Association of Pediatric Surgeons
Background and Aim: The third and fourth branchial cleft and pouch anomalies are the rarest among the anomalies of branchial arches and can pose diagnostic and management challenges in pediatric patients.

Giant cyst of the second branchial arch in an adult: case report and literature review [PDF]

Revista Brasileira de Cirurgia Plástica, 2023
Introduction: The branchial arches are the embryological precursors of the face, neck, and pharynx. Branchial arch anomalies are the second most common congenital head and neck lesions in children.

Ectodermal Wnt signaling, cell fate determination, and polarity of the skate gill arch skeleton

eLife, 2023
The gill skeleton of cartilaginous fishes (sharks, skates, rays, and holocephalans) exhibits a striking anterior–posterior polarity, with a series of fine appendages called branchial rays projecting from the posterior margin of the gill arch cartilages ...

A Case Report and Literature Review of Bilateral Cervical Chondrocutaneous Branchial Remnants

Case Reports in Dermatological Medicine, 2023
Chondrocutaneous branchial remnants (CCBRs) are rare congenital heterotopic tissue formations originating from the first or second embryonic branchial arches.

Congenital Parotid Fistula: Surgical Management in Two Infants and Review of Literature

Journal of Indian Association of Pediatric Surgeons, 2021
Congenital salivary gland fistulas are uncommon. They develop as a result of abnormalities of the first and second branchial arches. Operative and nonoperative methods of management have been described.

The signature of fusion between the embryological derivatives of the first and second branchial arches within the ossicular chain in MDCT

The Egyptian Journal of Radiology and Nuclear Medicine, 2018
The embryological precursors of the ossicular chain of the middle ear in humans are still a matter of debate. Both classical interpretation and dual-arch interpretation are strong hypothesis.
