目的 探讨不同品系小鼠瘤株跨系移植后移植瘤的生长转移情况,以及建立跨系小鼠肿瘤模型的可能性.方法 不同品系来源的H22、S180、U14、FC、Ca761、SMG-A和DCS小鼠瘤株分别接种于C57BL/6J、ICR或KM小鼠皮下,观察小鼠体内成瘤和转移情况,绘制生长曲线.结果 H22瘤株移植到C57BL/6J和ICR小鼠体内成瘤率均为100%.第17天时,C57BL/6J和ICR小鼠的瘤重分别为(2.8±0.4)g和(1.5±0.5)g,差异有统计学意义(P<0.001).S180瘤株在C57BL/6J小鼠体内的成瘤率为100%,肿瘤稳定生长.U14瘤株接种于C57BL/6J和KM小鼠后第32天,C57BL/6J小鼠体内移植瘤瘤重[(10.2±2.2)g]低于KM小鼠[(12.6±3.4)g,P=0.002].接种U14瘤株的C57BL/6J和KM小鼠均出现肺和淋巴结转移.FC、Ca761和SMG-A瘤株接种于C57BL/6J小鼠后不能成瘤或成瘤后完全消退.DCS瘤株接种于C57BL/6J小鼠也有部分肿瘤发生消退,未消退的肿瘤在C57BL/6J小鼠体内连续传代,获得亚克隆DCS-C57瘤株,其在C57BL/6J小鼠稳定生长,成瘤率和肺转移率均为100%.结论 小鼠瘤株跨系体内移植后,分化差、恶性程度高的瘤株可成功建立移植瘤.免疫原性强的瘤株即使成瘤也会消退,无法跨系建立移植瘤.出现肿瘤部分消退的瘤株经连续传代后,可获得稳定的移植瘤模型.
目的 探討不同品繫小鼠瘤株跨繫移植後移植瘤的生長轉移情況,以及建立跨繫小鼠腫瘤模型的可能性.方法 不同品繫來源的H22、S180、U14、FC、Ca761、SMG-A和DCS小鼠瘤株分彆接種于C57BL/6J、ICR或KM小鼠皮下,觀察小鼠體內成瘤和轉移情況,繪製生長麯線.結果 H22瘤株移植到C57BL/6J和ICR小鼠體內成瘤率均為100%.第17天時,C57BL/6J和ICR小鼠的瘤重分彆為(2.8±0.4)g和(1.5±0.5)g,差異有統計學意義(P<0.001).S180瘤株在C57BL/6J小鼠體內的成瘤率為100%,腫瘤穩定生長.U14瘤株接種于C57BL/6J和KM小鼠後第32天,C57BL/6J小鼠體內移植瘤瘤重[(10.2±2.2)g]低于KM小鼠[(12.6±3.4)g,P=0.002].接種U14瘤株的C57BL/6J和KM小鼠均齣現肺和淋巴結轉移.FC、Ca761和SMG-A瘤株接種于C57BL/6J小鼠後不能成瘤或成瘤後完全消退.DCS瘤株接種于C57BL/6J小鼠也有部分腫瘤髮生消退,未消退的腫瘤在C57BL/6J小鼠體內連續傳代,穫得亞剋隆DCS-C57瘤株,其在C57BL/6J小鼠穩定生長,成瘤率和肺轉移率均為100%.結論 小鼠瘤株跨繫體內移植後,分化差、噁性程度高的瘤株可成功建立移植瘤.免疫原性彊的瘤株即使成瘤也會消退,無法跨繫建立移植瘤.齣現腫瘤部分消退的瘤株經連續傳代後,可穫得穩定的移植瘤模型.

Objective Mouse tumors were subcutaneously transplanted into different mouse strains and their growth and metastatic properties were checked,to explore the possibility of establishing animal tumor models in different mouse strains other than their normal host strains.Methods Seven mouse tumor cell lines:H22,S180,U14,FC,Ca761,SMG-A and DCS were transplanted into C57BL/6J,ICR or KM mice,and their tumorigenicity,growth and metastasis were recorded and analyzed.Results The tumor formation rate of H22 cells in both the C57BL/6J and ICR mice was 100%,but the growth of H22 tumors was significantly faster in the C57BL/6J (2.8 ±0.4)g than in the ICR mice (1.5 ±0.5)g at the 17th day after transplantation (P <0.001).The S180 tumors grew stably in C57BL/6J mice and the tumor formation rate was 100%.The U14 inoculated into C57BL/6J and KM mice showed both lymphatic and lung metastasis and formed significantly larger tumors in KM mice [(12.6 ± 3.4)g] than that in the C57BL/6J mice [(10.2 ±2.2)g] on the 32rd day after transplantation (P=0.002).Transplantation of FC,Ca761,and SMG-A did not form tumors or the tumors were completely regressed later in C57BL/6J mice.DCS cells formed tumors in C57BL/6J mice,but some of the tumors regressed.The retained tumors were passaged in C57BL/6J mice,and the substrain DCS-C57 cells was established which showed stable growth and had a 100% tumor formation rate and 100% lung metastasis rate in C57BL/6J mice.Conclusions Cross-strain transplanted tumors can be successfully established by inoculation of poorly differentiated and highly malignant tumor cells into different mouse strains.Some highly immunogenic tumor cells may form tumor,however,the tumors are regressed later,and can not establish cross-strain transplanted tumors in other mouse strains.Stable transplanted tumor models can be obtained from the partially regressed tumors after continuous passages in vivo.
