Abstract
The Spemann organizer in amphibian embryos is a tissue with potent head-inducing activity, the molecular nature of which is unresolved. Here we describe dickkopf-1 (dkk-1), which encodes Dkk-1, a secreted inducer of Spemann''s organizer in Xenopus and a member of a new protein family. Injections of mRNA and antibody indicate that dkk-1 is sufficient and necessary to cause head induction. dkk-1 s a potent antagonist of Wnt signalling, suggesting that dkk genes encode a family of secreted Wnt inhibitors.
