Orthotopic models are based on the implantation of tumor cells directly into the organ of origin, which allows interaction between the cells and the surrounding host tissues.Here we describe a modified version of an orthotopic model that closely recapitulates the steps required for metastasis development in Ewing sarcoma: tumor cells are injected into the calf muscles of the mouse, and once the tumor reaches a certain volume, the muscles containing the tumor are surgically resected. This procedure involves a nonaggressive surgery of the muscle which allows for the survival of the mouse during a period of time that is long enough to enable the development of distant metastases. This spreading of tumor cells to metastatic sites in other organs takes place by a physiological mechanism similar to what occurs in human Ewing sarcoma.
