Figure 2From: Ovarian cancer: emerging concept on cancer stem cells Schematic diagram of signaling pathways that are involved in normal and cancer stem cell biology. Wnt, Shh and Notch1 pathways have been shown to contribute to the self-renewal of stem cells and/or progenitors in a variety of organs, including the ovarian system. When deregulated, these pathways can contribute to oncogenesis. Mutations of these pathways have been associated with a number of carcinomas.Back to article page
