AbstractBackground: Retinoic acid (RA) is a morphogenetically active signalling molecule thought to be involved in the development of several embryonic systems (based on its effect when applied in excess and the fact that it can be detected endogenously in embryos). Here, we adopt a novel approach and use the vitamin A-deficient (A−) quail embryo to ask what defects these embryos show when they develop in the absence of RA, with particular reference to the nervous system.Results We have examined the anatomy, the expression domains of a variety of genes and the immunoreactivity to several antibodies in these A− embryos. In addition to the previously documented cardiovascular abnormalities, we find that the somites are smaller in A− embryos, ...
