Taken together, while individual Dact genes were expressed in unique, at times species-specific locations, at least one member of the Dact1/3 gene group as well as of the Dact2/4 gene group was expressed in the paraxial mesoderm, the fin/limb buds and the mesenchyme of the pharyngeal arches in all vertebrates, suggesting that these are sites of original dact function.
According to current understanding, C cells of the mammalian thyroid gland develop from a subpopulation of cephalic neural crest cells that broadly populate the pharyngeal (or branchial) arches in all animals of the vertebrate series (Donoghue et al., 2008; Vickaryous and Hall, 2006).
Except in the ACH RB), SRB, RCCH, and ARCH in all other protocols described above, all SUs use the same algorithm to generate the CH sequences.
There were no significant differences in both arch indices for all ages, except for the 4 year-old group, where Brazilian children showed a higher Chippaux-Smirak index (lower plantar arches) (Tables 2 and 3).> -wrap-foot>> *Statistically higher values between German and Brazilian databases [t-test (parametric data) or Mann-Whitney test (non-parametric data), p < 0.05].
A sample of 18 Sprague-Dawley rats was divided into three groups; a 5-mm critical-sized bone defect was made in both zygomatic arches of all subjects.
An excessive number of fingerprint arches was present in all affected males and females in K8070 but was not noted in the other kindreds.
A narrow aortic arch was visualized in all 8 fetuses who were scanned after 1995, when scanning of the aortic arch became mandatory in our institution.
A right aortic arch was present in all 10 animals.
A persistent right aortic arch was present in all examined cases, and an aberrant left subclavian artery was most commonly observed.
The arches are laid down in all vertebrates, six or more being found in cyclostomes and fishes; six are present in the embryos of tetrapods, but the first two are degenerate.
