液氮长期保存裸鼠移植瘤模型的应用黄靖香，顾峥，纪小龙北京解放军总医院病理科在人类肿瘤的实验研究工作中，需要通过动物模型的研究来解释肿瘤的发生、发展、转移、诊断治疗过程。建立理想的裸鼠移植瘤模型虽然难，要长期保存好有价值的动物模型更难。过去常用鼠间传代法保 Application of Long-term Preservation of Nude Mouse Xenograft Model with Liquid Nitrogen Huang Jingxiang, Gu Zheng, Ji Xiaolong Department of Pathology, Beijing PLA General Hospital In the experimental research of human tumors, it is necessary to explain the occurrence, development, metastasis and diagnosis of tumors by studying animal models Healing. Although it is difficult to establish an ideal nude mouse xenograft model, it is more difficult to preserve valuable animal models in the long term. In the past commonly used mouse passage method to protect
