    • 摘要: 目的进一步探讨采用人来源的骨肉瘤组织进行原位移植形成骨肉瘤动物模型的可行性。方法通过将组织完整的肿瘤组织原位移植到裸鼠胫骨,建立一种人骨肉瘤原位移植模型。从第3代人骨肉瘤皮下移植瘤中获得完整的肿瘤碎片,植入18只裸鼠的胫骨近端。移植后4周处死动物进行尸检,并对局部肿瘤生长和转移进行大体和病理检查。结果最终16只裸鼠发生了局部胫骨内骨肿瘤,2只裸鼠术后5 d内死亡,造模2周后裸鼠下肢可见肿瘤状组织形成。裸鼠胫骨移植瘤不仅在X射线上具有人类原发骨肉瘤的特征,而且在病理切片和免疫组化上也表现出了人类原发骨肉瘤的特性。结论人骨肉瘤可以在裸鼠胫骨进行原位移植,且这种模型可能与临床相似,可用于肿瘤局部生长、转移形成和治疗的研究。

    • 摘要: Aim To establish human U87-MG glioma model in nude mice brain and to observe the characteristics of the tumor growth. Methods Human U87-MG glioma cells were cultured in vitro. 5 μL of cell suspension containing 3.0 ×1010·L-1, 4.0×1010·L-1and 5.0×1010·L-1respectively was inocula-ted into the right caudate nucleus of 18 male nude mice brain un-der the guidance of stereotaxic apparatus, separately, whereas another 6 nude mice as the control group, were inoculated into the same volume of Hanks solution. The moving and survival state of rats with gliomas were observed. The examinations of the tumors formation, volumes, metastasis and histopathology were performed and the obtained brain samples were stained with HE and immunohistochemistry. Results All the tested rats of dif-ferent inoculation doses developed brain tumors without extracra-nial metastasis. The mean survival time of three groups was (46.50 ± 3.27) d,(38.50 ± 3.28) d and (30.67 ± 3.51) d,respectively.

    • 摘要: Background and purpose: Renal cell carcinoma is the most common form of kidney cancer, characterized by lack of early symptoms and high malignancy. This study aimed to establish orthotopic nude mice models of human renal cell carcinoma with high success rate and good repeatability. Methods: The four types of methods which were adopted to establish the orthotopic models of renal cell carcinoma were orthotopic injection of 786-0 and ACHN cell suspensions, orthotopic injection of primary cell suspensions obtained from the subcutaneous tumor tissues, renal subcutis orthotopic implantation into renal capsule and surgical subcutis orthotopic implantation into renal fascia. To gain insights into the tumorigenicity and the growth of transplantation tumors, the imageological examination (PET/CT), histological examination (H-E staining, immunohistochemistry staining) and biochemical analysis of blood were carried out. Results: In terms of the subcutaneous transplantation of human renal cell carcinoma models in nude mice, tumorigenic rate of ACHN cells (90%) was higher than that of 786-0 cells (30%). The tumorigenic incidences of 786-0 cell suspensions orthotopic injection, ACHN cell suspensions orthotopic injection, ACHN subcutis cellular suspensions orthotopic injection, ACHN subcutis orthotopic implantation into renal capsule and renal fascia were 33%, 80%, 90%, 100% and 20%, respectively. ACHN subcutis orthotopic implantation into renal capsule was the most effective approach. Imageological and histological results accorded with poorly differentiated renal cell carcinoma. Conclusion: Four orthotopic nude mice models of human renal cell carcinoma were successfully established. Among these methods, ACHN subcutis orthotopic implantation into renal capsule is the most effective approach, which provides an ideal model for the research on biological behavior of human renal cell carcinoma and its treatment.%背景与目的:肾细胞癌是最常见的肾脏恶性肿瘤,起病隐匿,恶性程度高.研究旨在建立成功率高、稳定的人肾细胞癌原位动物造模方法.方法:采用人肾细胞癌细胞(786-0、ACHN)进行细胞悬液原位注射法、皮下成瘤后引瘤原代细胞悬液原位注射法、皮下成瘤后引瘤组织块原位移植肾包膜下法及皮下成瘤后引瘤组织块原位移植肾周筋膜内法建立原位移植裸鼠模型,采用PET/CT、H-E染色、免疫组织化学染色及血清生化检测等手段观察成瘤率及肿瘤生长情况,评估4种方法的建模效果.结果:人肾细胞癌皮下移植瘤裸鼠模型,ACHN组成瘤率(90%)高于786-0组(30%);人肾细胞癌原位移植裸鼠模型,786-0原位注射组、ACHN原位注射组、ACHN皮下移植瘤引瘤后原代细胞原位注射组、ACHN组织块肾包膜下包埋组和ACHN组织块肾周筋膜内包埋组的成瘤率分别为33%、80%、90%、100%和20%,其中以ACHN皮下成瘤后引瘤组织块原位移植肾包膜下法成瘤率最高,影像学及病理组织学检查结果显示符合低分化肾细胞癌.结论:成功建立4种人肾细胞癌原位移植裸鼠模型,其中以ACHN皮下成瘤后引瘤组织块原位移植肾包膜下法成瘤效果最佳,为肾细胞癌发病机制及靶向治疗的进一步研究提供理想的动物模型.

Methods The BALB/c nude mice were anesthesized by Matrx VIP 3000 type gas anesthesia systems. Orthotopic gastric cancer models were established by embedding method, thread?ligation method or gastric bursa method in the nude mice.

Samples of the transplanted tumor tissues for histological examination were taken at 28 days after transplantation. Results The orthotopic gastric cancer model was successfully established by embedding method. Compared with the models prepared by other commonly used methods, it showed obvious advantages such as a high success rate of transplantation, simple operation, short time, less difficulty, and less direct contact of the implanted tumor tissue with other organs, etc. Conclusions Large amount of mouse models of orthotopic gastric cancer can be prepared rapidly by the embedding method, thus, provide a convenient tool for related research of gastric cancer in future.
