Abstract:
BACKGROUND:Urine-derived stem cels are most likely to come from the kidney tissue, and therefore, these cels 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 cels on chronic nephropathy rats.
METHODS:The fresh urine samples of healthy people were colected, and then human urine-derived stem cels 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 cel 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 histomorphologicaly in each group.
RESULTS AND CONCLUSION: Human urine-derived stem cels were found to remarkable improve rat’s renal function as wel 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 cels were also markedly reduced in the experimental group. To conclude, human urine-derived stem cels can improve the renal function of chronic nephropathy rats.
