Purpose of the Study:

  • To elucidate the distinct functions of Wnt proteins.
  • To understand Wnt involvement in cell fate and behavior modulation during vertebrate development.
  • To explore Wnt interactions with other signaling pathways.

Main Methods:

  • Comparative genetic and cell biological approaches across different organisms.
  • Analysis of Wnt protein sequences and expression patterns.
  • Gain-of-function and loss-of-function studies in vertebrate models.
