Blelloch watched—day and night—as the cells of developing worms migrated through their bodies, observing what went wrong when certain genes were knocked out. He learned, for example, that the distal tip cells of worms carrying gon1, a mutation in a matrix metalloprotease gene, failed to migrate properly in the gonad, resulting in a misshapen organ.
