(2013) mentioned that, middle ear ossicles are visible as foci of mesenchymal condensation within the embryonic branchial arches. Also in birds, the columellar anlage of Bubulicus ibis appeared as human stapedial anlage (Salah EL-Din and Dakrory, 2015). Prenatal development of the sound trans...
Typically, there are six arches in embryos of vertebrates; in the lower vertebrates, they bear gills; in the higher vertebrates (e.g., human embryos), they appear transiently and give rise to specialized structures in the head and neck. Synonym(s): branchial arch. Medical Dictionary for ...
Fig. 1: Induction of NCC (neural crest cell)-like cells in the aggregates derived from hPSCs (human pluripotent stem cells). a Scheme of the differentiation culture for the induction of NCC-like cells. b Immunostaining of the day-5 aggregate with antibodies for SOX10 (green), PAX6 (red)...
First recorded in 1795–1805;branchi-+-al1 Discover More Example Sentences Now, a group of Kyoto University researchers have produced neural crest cell-rich aggregates from human pluripotent stem cells and developed a method to differentiate them in cell populations with a branchial arch-like gene...
Anatomy of the Human Body. 1918.12. The Branchial RegionThe Branchial or Visceral Arches and Pharyngeal Pouches.—In the lateral walls of the anterior part of the fore-gut five pharyngeal pouches appear (Fig. 42); each of the upper four pouches is prolonged into a dorsal and a ventral ...
We report the cloning, chromo- somal localization, and analysis of the expression pattern of epicardin, a member of the basic helix- loop-helix (bHLH) family of transcription factors. Within its bHLH domain, the human and murine epicardin genes were most similar to paraxis, a bHLH gene ...
Pax8, a transcription factor crucial for the development of follicular cells, is expressed in the fourth pharyngeal pouch and the ultimobranchial body in human embryos. Pax8 expression is also detected in the ultimobranchial remnants of Eya1 and Hes1 null mutant mice. To determine whether the C ...
A human calcitonin-like molecule in the ultimobranchial body of the amphibia (Rana pipiens) As assessed by radioimmunoassay, and high performance liquid chromatography (HPLC), frog ultimobranchial calcitonin was found to be similar to synthetic hu... R.,Perez-Cano,F.,... - 《Cellular & Molecu...
Gill arches were also collected from control and 1 h exposed fish and fixed in z-fix (Anatech Ltd.) overnight then stored in 70% ethanol until processing. Molecular Methods. Real time PCR primers were developed for nbc and vha (β-subunit), whereas prim- ers for nhe1, nhe2...
HOXA3 was also expressed in the posterior half of the second branchial arches (Figure 1B,E, black arrowheads), in addition to the 3rd and 4th branchial arches. This signal in the second branchial arches appeared faintly at st-20 (data not shown); but at st-21, intense signals were ...
