Abstract: Zebrafish (Danio rerio) is a small fish with distinctive black and yellow stripes that form on its body and fins due to the interaction of different pigment cells. Working closely with the biological data, we present an agent-based model for these stripes that accounts for the migration, differentiation, an death of three types of pigment cells on the zebrafish body. We also explore stripe formation on the caudal fin, where bone rays and fin growth seem to help direct pigment cell placement. The development of both wild-type and mutated patterns will be discussed, as well as the non-local continuum limit associated with the model. This research is joint work with Björn Sandstede.
