History
Etymology
Borrowed from German Dickkopf (“stubborn person”, literally “thick head”), from the fact that Dickkopf-related protein 1 (DKK1), one of the dickkopf proteins, was found to be required for head formation in embryos. The word was coined by Andrei Glinka, Wei Wu, Hajo Delius, A. Paula Monaghan, Claudia Blumenstock, and Christof Niehrs in a 1998 article published in Nature: see the quotation.
