Xenograft Mouse Model of Human Uveal Melanoma

[Abstract]  Uveal melanoma (UM) is a malignant intraocular tumor in adults. Metastasis develops in almost half of the patients and over 90% of the metastases are in the liver. With the advances in molecular targeting therapy for melanoma, a proper metastasis animal model is of increasing importance for testing the accuracy and effectiveness of systemic therapies. Here, we describe a xenograft model for mimicking human UM liver metastasis by injecting human UM cells into the vitreous cavity in nude mice. The athymic nude mice are immunocompromised and suitable for xenograft tumor growth and metastasis, and intravitreal injection of cells is a quicker and easier operation under a binocular scope, thereby it is simple and effective to test human UM growth and metastasis. [摘要]  葡萄膜黑色素瘤(UM)是成人中的恶性眼内肿瘤。 几乎一半的患者发生转移,90%以上的转移灶位于肝脏。 随着分子靶向治疗黑色素瘤的进展,正确的转移动物模型对于检测全身治疗的准确性和有效性越来越重要。 在这里,我们描述了一个模仿人类UM肝转移的异种移植模型,通过将人类UM细胞注入裸鼠的玻璃体腔中。 无胸腺裸鼠具有免疫功能低下,适合异种移植瘤的生长和转移,在双眼镜下,玻璃体内注射细胞更快,更容易手术,因此简单有效地检测人类的UM生长和转移。

【背景】UM是成人中最常见的原发性眼内肿瘤,发病率在世界范围内为5至10个/百万(Singh et al。,2011)。几乎一半的患者在初始诊断即使在治疗或/和移除原发性肿瘤后15年内也发生转移(Kujala等人,2003; Weis等人, 2016)。在超过4%的患者中,诊断时已经存在微转移(Finger等人,2005)。这个数字可能会被低估,因为早期的UM检测的限制。目前的药物治疗,例如眼球摘除术,斑块近距离放疗,质子束照射已经成功地去除或抑制早期的局灶性眼内UMs(Dogrusoz等人,2017)。但是一般来说,UM对标准的化学疗法具有抗性,迄今为止还没有有效的全身治疗可用于转移性病变(Goh和Layton,2016; ...

[Abstract]  In the Whole Spleen Flow Cytometry Assay, we used splenocytes directly ex vivo for stimulation with a variety of TLR ligands. The splenocytes were stimulated for a total of 4 hours, then stained for intracellular cytokines. We then examined cytokine production via flow cytometry. This allowed us to compare the responses of minimally manipulated primary macrophages/monocytes and conventional dendritic cells. [摘要]  在全脾流式细胞术测定中,我们直接使用脾细胞离体用各种TLR配体刺激。 将脾细胞刺激总共4小时,然后对细胞内细胞因子染色。 然后我们通过流式细胞术检查细胞因子产生。 这使我们能够比较最小操纵的原代巨噬细胞/单核细胞和常规树突状细胞的反应。
