Tumor Growth Analysis of Ewing Sarcoma Cell Lines Using Subcutaneous Xenografts in Mice.

Subcutaneous murine xenograft models are one of the most commonly used in vivo experimental methods in the cancer research field. Due to the lack of appropriate animal models for Ewing sarcoma, subcutaneous murine xenograft models currently offer the simplest way to investigate antineoplastic effects of therapeutics or biological functions of target genes in vivo. In order to properly carry out tumor growth analysis via subcutaneous xenografts of Ewing sarcoma cells many factors should be taken into account beforehand at the planning phase of experiments. Therefore, in this chapter we describe in detail a widely used procedure for subcutaneous injection in mice, focusing on the specific characteristics of Ewing sarcoma cell lines.
