该协议描述了一种从肿瘤层培养开始分离小鼠横纹肌瘤原发细胞、肿瘤球的形成和治疗以及异体移植的可重复方法。
Rhabdomyosarcoma 是一种罕见的软组织肉瘤形式,以组织学特征为组织形态和 myogenic 标记的表达。然而,鉴于这些肿瘤的不同亚型的存在,以及促成其形成的刺激的异质性,确定原生细胞是非常具有挑战性的。在这里,我们描述了从从小鼠新鲜收获的肿瘤组织开始鉴定罗巴多米瘤起源细胞的可重复和可靠的方法,这种测定是肿瘤球形成测定。
肿瘤球形成分析的主要优点是,它依赖于已知存在于肿瘤原细胞中的细胞特性,它也可用于特定细胞群体的扩张和富集。此外,其球体结构模仿肿瘤环境,因此可用作药物筛选研究。这种方法有可能应用于其他类型的肿瘤,因为它不需要事先了解分子标记,但它可能需要优化培养条件。
