Head Morphogenesis and WNT Signalling Function

Funded Activity Summary

One of the most critical steps in embryonic development is the assembly of the different tissue components into a three-dimensional structure in order to build a major body part of the foetus. In the development of the head, this form-shaping process undertaken by different cell populations is coordinated by genetic activity that is triggered by signals received by cells. The objective of our research is to understand how one of the many signalling mechanisms, WNT signalling, works in making the head and face of the embryo. We will study the development of embryos of mice in which mutations have been introduced experimentally in genes that code for factors of the WNT signalling pathway. Understanding the complexity of tissue interactions and the interplay of molecular mechanisms of head formation in the embryo is a major challenge. However, knowledge of the processes in animal models will contribute to a better delineation of the role of signalling in normal head development. It will also help to direct the focus of future clinical investigations to the most relevant genetic determinants of birth defects of the head and face, which is present in about 8 per 10,000 births in Australia.
