Pattern Formation in Growing omains

Modelling pigmentation patterning in angelfish and zebrafish

31st October 2005

Abstract

The process by which the early embryo is transformed from an undifferentiated, and effectively homogeneous, population of cells into a fully formed and complex organism has long fascinated both experimentalists and theoreticians alike.

Skin pigmentation markings are a particularly elegant and striking example of embryonic pattern formation. In certain fish, these patterns can be observed from early early embryonic through to full adult stages, thus providing a model for studying the coupled effect of patterning and embryonic growth. In this talk I will discuss the application of mathematical models to explain the development and growth of pigmentation patterns in anglefish and zebrafish.
