由于EWS-FLI 1的过度表达诱导细胞凋亡而不足以诱导肿瘤,因此建立尤文肉瘤模型具有挑战性。因此,获得耐受EWS-FLI 1表达的尤文肉瘤来源细胞是重要的。在这里,我们描述了EWS-FLI 1表达的尤文肉瘤小鼠模型的产生,通过选择胚胎软骨祖细胞,eSZ细胞含有尤文肉瘤前体。
Modeling Ewing sarcoma is challenging, since overexpression ofEWS-FLI1induces apoptosis and is not sufficient for tumor induction. It is therefore important to obtain the cell-of-origin of Ewing sarcoma that is tolerant ofEWS-FLI1expression. Here we describe the generation of theEWS-FLI1-expressing mouse model for Ewing sarcoma by selecting embryonic chondrogenic progenitor, eSZ cells that contain Ewing sarcoma precursors.
