The Dlx homeobox gene family is of ancient origin, with apparent ancestral developmental functions in both nervous system regionalization and appendage (limb) outgrowth. Additional roles in inner ear and craniofacial development were likely acquired by the Dlx gene family during the course of animal
## Abstract This study describes a whole embryo and embryonic field analysis of retinoic acid's (RA) effects upon __Xenopus laevis__ forebrain development and differentiation. By using in situ and immunohistochemical analysis of __pax6__, __Xbf1__, and tyrosine hydroxylase (TH), gene expression dur
