Roles of Sox factors in neural determination: conserved signaling in evolution?
Int J Dev Biol.
2001.
Abstract
Neural differentiation in amphibian embryos is initiated by the neural inducers emanating from the Spemann-Mangold organizer. The fate of uncommitted ectoderm is determined by graded BMP activity along the dorsal-ventral axis. Several transcriptional regulators acting in early neural differentiation have been identified, including Sox, Zic, Pou, HLH and Fox factors. In this paper, I review recent molecular studies on neural determination, focusing mainly on Sox factors. I also discuss the possible conservation of regulatory factors in neural differentiation, comparing Xenopus and Drosophila counterparts.
