Angiogenic Effect of Endothelial Progenitor Cells Transfected with Telomerase Reverse Transcriptase on Peritubular Microvessel in Five Out of Six Subtotal Nephrectomy Rats
2012
Renal disease is caused by tubular interstitial injury and renal interstitial fibrosis. Previous studies have shown that transplantation of endothelial progenitor cells (EPCs) may provide an appropriate treatment for repair and reversing renal pathology. However, EPCs are typically low in abundance and have poor replication ability. Therefore, the this study investigated the use of EPCs transfected with the telomerase reverse transcriptase (TERT) in rats that had undergone five out of six subtotal nephrectomy. This study determined the effects of EPC transplantation on renal function, renal interstitial fibrosis, and peritubular capillary angiogenesis. Five groups of rats were investigated: sham group, model group (five out of six subtotal nephrectomy), EPCs-N group (transplantation with EPCs), pZ-TERT-EPCs-N group (transplantation with EPCs transfected with TERT), and pZ-EPCs-N group (transplantation with EPCs transfected with empty plasmid). At weeks 4, 8, and 12 after transplantation, renal function, r...
