Skeletal Development: Making and Shaping Bones
The aim is to understand the role of the Fat4-Dchs1 signalling pathway during mammalian development. This is an essential pathway for human development as mutations in Fat4 and Dchs1 result in Van Maldergem’s syndrome characterized by a number of developmental defects including altered craniofacial development. Fat4 and Dchs1 act together to coordinate cell polarity and growth via the Hippo pathway. Fat4 and Dchs1 mouse mutants have alterations in cell organization and proliferation which alter the development, size and shape of bones. The bones in mutants can be shorter and wider (e.g. sternum) or smaller (e.g. cranial bones). This project will investigate how Fat4 and Dchs1 control skeletal development by analysing cell shapes and organization within developing bones and the identification of transcriptional targets of Fat4-Dchs1 signalling.
Mechanical regulation of embryonic development
In adult tissues, mechanical forces control cell behaviours such as migration, epithelial-mesenchymal transformations and Stem cell differentiation. Despite the crucial roles of mechanical forces in adult tissues, our understanding of how mechanical signals influences embryonic development is little understood. Using in vitro and in vivo model systems and Atomic Force Microscopy, the aim of this research project is to understand the role of mechanical forces, such as matrix stiffness, in the regulation of gene expression and cell differentiation during embryonic development.
Intracellular Mechanisms of Dchs1-Fat4 signalling
Fat4 and Dchs1 act together to coordinate cell polarity and growth via the Hippo pathway. The aim of this project is to understand how Dchs1-Fat4 regulate these two very distinct cellular outcomes using in vitro and in vivo model systems. We aim to identify intracellular binding partners and transcriptional effectors of this pathway.
