Mesenchymal stem cells (MSCs) are abundant throughout the body and regulate signaling within tumor microenvironments. Wnt signaling is an extrinsically regulated pathway that has been shown to regulate tumorigenesis in many types of cancer. After evaluating a panel of Wnt activating and inhibiting molecules, we show that primary human MSCs increase the expression of Dkk-1, an inhibitor of Wnt signaling, into the extracellular environment following chemotherapy exposure in a p53-dependent manner. ...[more]
