Gonadal development of quail embryos was examined histologically using histological and histochemical methods. In the present study, quail embryos were studied at various stages of incubation period based on phases of gonadogenesis. Germ cell migration was observed on day 3-4 but gonadal differentiation and gonadal function were observed on day 6-8 and day 11-14, respectively. During germ cell ...

The levels of the neural axis from which parasympathetic and orthosympathetic neurons and adrenomedullary cells are derived under normal developmental conditions were determined in avian embryos by a biological labeling technique. The technique is based on nuclear differences between two species of birds, the chick and the quail. In quail interphase nuclei a part of the chromatin is condensed i...

ASIP is an important pigmentation gene responsible for dorsoventral and hair-cycle-specific melanin-based color patterning in mammals. We report some of the first evidence that the avian ASIP gene has a role in pigmentation. We have characterized the genetic basis of the homozygous lethal Japanese quail yellow mutation as a >90-kb deletion upstream of ASIP. This deletion encompasses almost the ...

Knee joint development and its morphogenetic events have been studied in human, chicken and other animal models and differences have been found in the pattern of the knee joint morphogenesis among the studied species. According to the small number of studies which have focused on the chronology of knee morphogenesis, a "morphogenetic timely pattern" is hard to suggest. Quail is an animal model ...

Fragments of quail wing bud containing myogenic cells of somitic origin and fragments of quail sphlanchopleural tissue were introduced into the interior of the wing bud of fowl embryo hosts. No movement of graft into host tissue occurred in the control, but myogenic cells from the quail wing bud fragments underwent long migrations in an apical direction to become incorporated in the developing ...

We describe here conditions allowing the selective growth in culture of embryonic capillary endothelial cells from quail yolk sac. Such cultures were set up to characterize an antigen present on the endothelial cell surface and to study whether it was secreted in the culture medium. This antigen, MB1, was previously evidenced by a monoclonal antibody raised to quail IgM heavy chain. It is prese...

A 2×2×2 factorial design experiment was carried out with two levels of protein (20 and 22%), two levels of lysine (1.05 and 1.15%) and two levels of total sulfur amino acids (TSAA) (0.8 and 0.9%) to investigate their effect on growth performance and carcass characteristics of growing Japanese quail. A total number of 408 unsexed one week old Japanese quail chicks were randomly distributed into ...

HemoglobIn ontogenic changes have been studied In chimeras composed of a quaIl embryo grafted on a chIck yolk sac. From the blood of such chlmeras, quaIl erythrocytes are separated from chIck by means of a specific Immune hemolytlc technIque, thus yielding two populations of red cells, one derIving from yolk sac stem cells and the other from intraembryonlc stem cells. Both populations comprIse ...
