Research summary

Our current projects include:

  • The embryological origin of radial aplasia
  • Fate mapping the limb bud and the control of co-ordinated development of limb anatomy
  • Developing novel avian transgenic tools for developmental biology
  • The evolution of limb pattern in birds
  • The function of TALPID3

Current research interests

Understanding the generation of the patterned embryo from a single fertilised cell has always captured my interest and imagination. The developing limb bud is a classical model for understanding biological networks which regulate embryonic morphogenesis. The research in my group has utilizes naturally occurring polydactylous chicken mutants (which extra toes) to understand how the limb bud is patterned. We are particularly interested in the action of the Sonic Hedgehog (SHH) protein. This protein is produced in the cells which will eventually become the little finger and ulna. These cells use SHH to tell the other cells of the developing limb how many fingers and toes to make and what type of finger they should become. We are interested in understanding the basic principals of embryonic pattern formation and how this is inportant for human and animal health. Research Interests The Davey Group examines the causative alterations of gene expression which lead to variations in phenotype using comparative anatomy, genomics and embryonic manipulation of avian species. She has expertise in gene expression analysis, particularly the molecular anatomy of the developing limb bud.
