Differential Cellular Responses to Hedgehog Signalling in Vertebrates-What is the Role of Competence?J Dev Biol 4
A surprisingly small number of signalling pathways generate a plethora of cellular responses ranging from the acquisition of multiple cell fates to proliferation, differentiation, morphogenesis and cell death. These diverse responses may be due to the dose-dependent activities of signalling factors, or to intrinsic differences in the response of cells to a given signal-a phenomenon called
