| Abstract | ||
| Background: The limbs bud development is induced by the apical ectodermal ridge. The trace elements were found to have important role in biological growth of tissues such as tumor tissues. Objectives: This study was done to reveal the possible biological role of trace elements as zinc, copper, and magnesium in the limb development induced by the apical ectodermal ridge. Methods: Chick embryos of Hamburger and Hamilton stages 20-26 were used. Trace elements were measured in limb buds with and without apical ectodermal thickening. Results and discussion: The decrease in zinc concentration found in limb buds tissues having no apical ridge suggested a relationship between this trace element and the inductive effect produced by the apical ectoderm for limb buds formation. The detectable concentration of copper only in buds having no apical ridge was correlated with the embryonic organization of the limb buds. The lower magnesium concentration in the limb buds was considered as a criterion for the metabolism accompanies the functioning apical ectoderm during the embryogenesis of the limb buds. Conclusions: Trace elements may have a significant role in the embryonic process of budding. Keywords: Limb buds, trace elements, zinc, copper, magnesium, development. | ||
