Cyclosporine Effects on Chick Limb Bud Mesenchyme and DNA Content
Background: Cyclosporine A (CsA) is a powerful immunosuppressive agent, which is used for the prevention of allograft rejection and for the treatment of autoimmune diseases. Many transplant recipients must take this medicine for the rest of their lives. Females in reproductive age group on prolonged CsA therapy have legitimate concerns about drug effects on pregnancy. Objective: To explore Cs...
متن کاملAnalysis of Hox gene expression in the chick limb bud.
The vertebrate Hox genes have been shown to be important for patterning the primary and secondary axes of the developing vertebrate embryo. The function of these genes along the primary axis of the embryo has been generally interpreted in the context of positional specification and homeotic transformation of axial structures. The way in which these genes are expressed and function during the de...
متن کاملRetinoic acid and chick limb bud development.
The chick limb bud is a powerful experimental system in which to study pattern formation in vertebrate embryos. Exogenously applied retinoic acid, a vitamin A derivative, can bring about changes in pattern and, on several grounds, is a good candidate for an endogenous morphogen. As such, the local concentration of retinoic acid might provide cells with information about their position in relati...
متن کاملA quantitative analysis of the effect of excision of the AER from the chick limb-bud.
The effect of removal of the apical ectodermal ridge from the early chick limb-bud is re-examined using a new quantitative method of analysis of results. The concept of the proximo-distal sequence of laying down of parts is confirmed and evidence is presented that this proceeds as a continuous process, there being a gradual change in the level specified from one cell to another at a more distal...
