免疫缺陷小鼠正在成为人类干细胞和肿瘤研究的宝贵工具。在这项研究中,我们建立了具有C57/BL6和Balb/c遗传背景的RAG-2/JAK3双缺陷(RAG-2−/−JAK3−/−)小鼠,并比较了人类淋巴造血细胞的植入率。成功地将人脐带血来源的CD34+造血干细胞移植到Balb/c RAG-2−/−JAK3−/−小鼠体内,而在C57/BL6 RAG-2−/−JAK3−/−小鼠中的植入率要低得多。人外周血单核细胞移植也导致了同样的趋势。因此,Balb/c背景提供了比C57/BL6背景更好的植入能力,并为人类造血细胞的植入提供了一个有吸引力的模型。
Immunodeficient mice are becoming invaluable tools in human stem cell and tumor research. In this study, we generated Rag-2/Jak3 double-deficient (Rag-2−/−Jak3−/−) mice with a C57/BL6 and Balb/c genetic background and compared the human lymphohematopoietic cell engraftment rate. Human cord blood-derived CD34+ hematopoietic stem cells were successfully engrafted into Balb/c Rag-2−/−Jak3−/− mice; however, the engraftment rate was far lower in C57/BL6 Rag-2−/−Jak3−/− mice. Transplantation of human peripheral blood mononuclear cells resulted in the same tendency. Thus, a Balb/c background offers superior engraftment capacity than a C57/BL6 background and provides an attractive model for human hematopoietic cell engraftment.
