When Kaufman, Zon and colleagues looked to see what was different about these early cancer cells, they found that crestin and the other activated genes are the same ones turned on during zebrafish embryonic development — specifically, in the stem cells that give rise to the pigment cells known as melanocytes, within a structure called the neural crest.

This program normally shuts off after embryonic development, but occasionally — for reasons not yet known — crestin and other genes in the program turn back on in certain cells.
