目前尚无可重复的肾细胞癌(RCC)脊柱转移动物模型,可供对人类疾病进行实验室研究。在本报告中,我们描述了一种使用人类肿瘤细胞系可靠地再现 RCC 脊柱转移的动物模型。采用后路手术方法将肿瘤细胞植入免疫抑制小鼠的椎板中。肿瘤细胞植入12周后对组织学切片进行分析,以量化肿瘤生长的位置和程度。 RCC 异种移植物在治疗动物(8 只小鼠)中按照可重复的生长模式生长。植入后,肿瘤生长主要发生在前后尺寸。肿瘤细胞植入后8周,所有接受治疗的小鼠均出现可见的肿瘤生长。肿瘤细胞植入后12周的组织学相关性证实肿瘤生长主要涉及脊柱旁区域和椎板。我们的研究建立了人类肾细胞癌脊柱转移的原位模型。最终,这将有助于测试累及脊柱的肾细胞癌的靶向治疗。此外,该模型可以扩展为其他肿瘤细胞系开发类似的脊柱转移模型。
There is currently no reproducible animal model of renal cell carcinoma (RCC) spinal metastasis that allows for laboratory study of the human disease. In this report, we describe an animal model that reliably reproduces RCC spinal metastasis using a human tumor cell line. A posterior surgical approach was used to implant tumor cells into the lamina of immunosuppressed mice. Histology sections were analyzed 12 weeks after tumor cell implantation to quantify the location and extent of tumor growth. RCC xenografts grew in treated animals (8 mice) according to a reproducible pattern of growth. After implantation, tumor growth occurred primarily in the antero-posterior dimension. At 8 weeks after tumor cell implantation, there was visible tumor growth in all treated mice. Histologic correlation at 12 weeks after tumor cell implantation confirmed tumor growth involving primarily the paraspinal region and lamina. Our investigation resulted in an orthotopic model of human RCC spinal metastasis. Ultimately this will allow testing of targeted therapies for RCC with spinal involvement. Furthermore, this model can be expanded to develop similar spinal metastasis models for other tumor cell lines.
