Influence of the microenvironment on gene regulatory networks in Ewing sarcoma

Our research focuses on addressing the basic mechanisms of Ewing sarcoma development in children, with special emphasis on the contribution of the microenvironment, that may ultimately provide the basic knowledge for developing novel therapeutic approaches.
