immunodeficiency animals

The sources of human tumors ( transplanted to immunodeficiency animals ) are mainly biopsy tissues , surgically resected tumor specimens and human tumor cell lines .

人类肿瘤移植瘤（指移植于免疫缺陷动物）的来源有肿瘤活检组织，手术切除的肿瘤标本和人类肿瘤细胞系。

Objective : To establish an orthotopic transplantation model of human hepatocellular carcinoma in NOD-SCID mice and compared with the biological characteristics of nude mice to discuss the application value of the two immunodeficiency animals in xenograft transplantation of human hepatocellular carcinoma .

目的：建立人肝癌NOD-SCID小鼠原位移植模型，并通过和裸小鼠原位移植模型生物学特性的比较，对两种不同类型免疫缺陷动物在人肝癌异种移植方面的应用价值进行初步探讨。

And is negative for CD34 , CD45 , CD14 . Many investigators gain good results when they use MSCs as seed cells in bone tissue engineering to repair bone defect of animal model by autotransplantation or allotransplantation into immunodeficiency animals .

应用MSCs作为骨组织工程种子细胞的研究很多，在自体移植修复骨缺损动物模型和异基因移植修复免疫缺陷动物骨缺损模型实验中取得了良好的效果。
