The EGF ligand is the diffusible extracellular element involved in the process of vulval cell differentiation. It binds to the EGF receptor on the vulval precursor cells and initiates a signaling cascade that leads to their differentiation into vulval cells. The Notch pathway also plays a role in this process, but it is mediated by direct cell-to-cell contact rather than a diffusible ligand.
