August 2020 in “Stem Cell Research & Therapy” The study investigated the therapeutic potential of SIRT1-modified human umbilical cord mesenchymal stem cells (hUCMSCs) for treating peritoneal fibrosis, a complication of long-term peritoneal dialysis. By overexpressing SIRT1 in hUCMSCs, researchers found that these modified cells had a stronger anti-fibrosis effect compared to regular hUCMSCs. They significantly inhibited fibrotic gene expression, suppressed the epithelial-mesenchymal transition process, increased ultrafiltration volume, and restored the balance of bioincompatible factors in dialysis solutions. The mechanism involved reducing peritoneal inflammation and inhibiting the TGF-β/Smad3 pathway. The findings suggested that SIRT1-modified hUCMSCs could be a promising therapeutic strategy for peritoneal dialysis-induced peritoneal damage and fibrosis.
