A possible role of chorion protease in shell membrane degradation during development of quail embryos.
In the eggs of the quail Coturnix japonica, the limiting membrane demarcates the shell membrane at the interface with the albumen and decreases in width during the hatching process. This study was done to identify agents that affect the width of this limiting membrane. Zymography tests on extracts from extraembryonic tissues, yolk sacs, or chorioallantoic membranes, or all three, showed proteol...
متن کاملerg gene(s) expression during development of the nervous and muscular system of quail embryos
The expression pattern of K(+) currents is the principal regulator of electrical activity during development of the nervous and muscular system. We report here a study showing the expression pattern of HERG K(+) currents-encoding (erg) genes in various nervous and muscular tissues at different stages of quail embryo development.
متن کاملThe effects of actinomycin D on the early development of quail and chick embryos.
In agreement with previous work it has been found that treatment of chick embryos at an early stage of development with small concentrations of actinomycin D (20-40 x 10~ M) produces abnormalities of the brain, neural tube and somites but allows near normal development of heart and blood islands. Similar effects are produced on quail embryos by even smaller concentrations of actinomycin D (0-8-...
متن کاملThe development of hepatogenic potency in the endoderm of quail embryos.
Hepatogenic potency of the endoderm is detectable in the anterior half of the endoderm of quail embryos older than 2-somite stage when endodermal fragments are cultured with or without heterologous chick mesenchymes, in the coelomic cavity of 3-day chick embryos. On the other hand, the posterior half of the endoderm never has hepatogenic potency. The hepatogenic potency of the endoderm is gradu...
متن کاملMicro-magnetic resonance imaging study of live quail embryos during embryonic development
Eggs containing live Japanese quail embryos were imaged using micro-magnetic resonance imaging (μMRI) at 24-h intervals from Day 0 to 8, the period during which the main body axis is being laid down and organogenesis is taking place. Considerable detail of non-embryonic structures such as the latebra was revealed at early stages but the embryo could only be visualized around Day 3. Three-dimens...
