Building on our discussion of both signalling pathways and G-protein coupled receptors from a few weeks ago, this week we’re going to discuss the Wnt signalling pathway- a pathway which is crucial in aspects of development and can have widespread impacts on the cell. It all sounds rather intimidating, but there’s actually surprisingly few steps involved in this pathway- and we’re only going to be focusing on one part of the signalling network, which makes life a lot less complicated!
