文题释义:
尿源性干细胞:
是从尿液中分离培养出的具有良好增殖活性和多向分化能力的成体干细胞,研究表明其具有间充质干细胞的各种生物学特性,因尿源性干细胞具有来源不受限、制备过程简便、安全无创和成本低等特点,故其成为了细胞替代治疗和组织工程研究中更为理想的种子细胞来源。
检测移植入受体体内干细胞的3种方法:①Y染色体检测,即于雌性受体(动物或人)组织中检测到雄性供体来源的Y染色体阳性细胞;②绿色荧光蛋白转基因标记检测;③LacZ(β-半乳糖苷酶染色)标记检测。

 

摘要
背景:
尿源干细胞最可能的来源是肾脏组织,可能更加适应肾脏微环境,这为肾脏疾病的治疗提供了新思路。
目的:探讨人尿源干细胞对慢性肾病模型大鼠的治疗作用。
方法:收集健康人新鲜尿液,提取人尿源干细胞,进行体外培养。20只SD大鼠制备慢性肾病模型,实验组肾皮质内注射人尿源干细胞悬液,对照组肾皮质内注射生理盐水,另外取10只健康大鼠作为正常组。通过检测3组大鼠血清肌酐及肾小球滤过率判断尿源干细胞对肾功能的改善作用,并对3组大鼠肾脏进行组织形态学评估。
结果与结论:①尿源干细胞对肾功能具有改善作用,与对照组比较,实验组大鼠血清肌酐降低、肾小球滤过率升高;②尿源干细胞对肾脏的组织学形态有改善作用,与对照组比较,实验组大鼠肾脏组织中CD68阳性细胞明显减少,肾脏间质炎性细胞浸润减轻;③结果表明,人尿源干细胞对慢性肾病模型大鼠肾功能存在修复作用。

Abstract:

BACKGROUND: Urine-derived stem cells are most likely to come from the kidney tissue, and therefore, these cells are more adaptable to kidney microenvironment, providing a new option for the treatment of kidney diseases.
OBJECTIVE: To explore the therapeutic efficacy of human urine-derived stem cells on chronic nephropathy rats.
METHODS: The fresh urine samples of healthy people were collected, and then human urine-derived stem cells were extracted and cultured in vitro. Twenty Sprague-Dawley rats were used to prepare chronic nephropathy models, and given injection of human urine-derived stem cell suspension (experimental) or normal saline (control) into the renal cortex, respectively. Another 10 healthy rats were used as controls. Therapeutic effects on renal function were assessed by detection of serum creatinine level and glomerular filtration rate in the three groups. The kidney tissues of rats were taken and observed histomorphologically in each group.
RESULTS AND CONCLUSION: Human urine-derived stem cells were found to remarkable improve rat’s renal function as well as reduce the histomorphological changes in the kidney tissues of rats. Compared with the control group, the serum creatinine level was decreased while the glomerular filtration rate was increased significantly in the experimental group; CD68 expression and infiltration of interstitial inflammatory cells were also markedly reduced in the experimental group. To conclude, human urine-derived stem cells can improve the renal function of chronic nephropathy rats.
