BACKGROUND
Systemic lupus erythematosus (SLE) is a multisystem disease that is characterized by the appearance of serum autoantibodies. No effective treatment for SLE currently exists.
METHODS
We used human umbilical cord mesenchymal stem cell (H-UC-MSC) transplantation to treat B6.Fas mice.
RESULTS
After four rounds of cell transplantation, we observed a statistically significant decrease in the levels of mouse anti-nuclear, anti-histone, and anti-double-stranded DNA antibodies in transplanted mice compared with controls. The percentage of CD4(+)CD25(+)Foxp3(+) T cells in mouse peripheral blood significantly increased after H-UC-MSC transplantation.
CONCLUSIONS
The results showed that H-UC-MSCs could repair lesions in B6.Fas mice such that all of the relevant disease indicators in B6.Fas mice were restored to the levels observed in normal C57BL/6 mice.
背景
系统性红斑狼疮（SLE）是一种多系统疾病，其特征是出现血清自身抗体。目前尚无 SLE 的有效治疗方法。
方法
我们使用人脐带间充质干细胞（H-UC-MSC）移植来治疗 B6.Fas 小鼠。
结果
经过四轮细胞移植后，与对照组相比，我们观察到移植小鼠的鼠抗核、抗组蛋白和抗双链 DNA 抗体水平有统计学意义的下降。H-UC-MSC 移植后，小鼠外周血中 CD4(+)CD25(+)Foxp3(+)T 细胞的百分比显著增加。
结论
结果表明，H-UC-MSCs 可修复 B6.Fas 小鼠的损伤，使 B6.Fas 小鼠的所有相关疾病指标均恢复到正常 C57BL/6 小鼠的水平。
