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.
