The SOX family of transcription factors has been implicated in cell fate specification during embryogenesis. One member of this family, Sox9, has been shown to regulate both chondrogenesis and sex determination in the mouse embryo. Heterozygous mutations in Sox9 result in Campomelic Dysplasia (CD), a lethal human disorder characterized by autosomal XY sex(More)
The transcription factors of the Sox family play important roles in diverse developmental processes. A number of genetic studies have established that Sox10 is a major regulator of neural crest formation. Here, we report the cloning and functional analysis of the Xenopus Sox10 gene. Sox10 mRNA accumulates during gastrulation at the lateral edges of the(More)
The vertebrate inner ear develops from a thickening of the embryonic ectoderm, adjacent to the hindbrain, known as the otic placode. All components of the inner ear derive from the embryonic otic placode. Sox proteins form a large class of transcriptional regulators implicated in the control of a variety of developmental processes. One member of this(More)
The neural crest is a multipotent population of cells that arises at the neural plate border in the vertebrate embryo. We have previously shown that a member of the Sox family of transcription factors, Sox9, is a regulator of neural crest formation in Xenopus, as Sox9-depleted embryos failed to form neural crest progenitors. Here, we describe experiments(More)
