AB  - Dickkopf-1 (Dkk-1) is a potent head inducer in Xenopus. This effect can be attributed to its capability to specifically inhibit Wnt/beta-catenin signalling. Recent data point to a crucial role for Dkk-1 in the control of programmed cell death during vertebrate limb development. In this paper, we present a comparative expression analysis of Dkk-1, Bmp-4 and Sox-9 as well as data on the regulation of Dkk-1 by Wnt. Finally, we summarize the current knowledge of its potential function in the developing limb and present a model how the interplay of the Bmp, Fgf and Wnt signalling pathways might differentially regulate programmed cell death versus chondrogenic differentiation in limb mesodermal cells.
