In the present study, we analysed the preventive effects of culture supernatant of P-Epi in PF. Concentrated culture supernatant of P-Epi or human fibroblast-like PMCs (P-Fibro) or vehicles was injected into nude mice that had undergone mechanical scraping of the parietal and visceral peritoneum, and thickness and amount of adhesions were analysed. Although increased peritoneal adhesions and peritoneum thickening were observed in the vehicle-injected positive control group compared to the sham operation group, fewer number of adhesions and less thickness were observed in the mice treated with culture supernatant of P-Epi, but not P-Fibro, compared to the vehicle-injected positive controls. Immunofluorescent analysis revealed that the expression of extracellular matrix, type I collagen and fibronectin, was lower in the mice treated with culture supernatant of P-Epi than in the vehicle-injected positive controls. In addition, exosomes from P-Epi significantly reduced transforming growth factor-β (TGF-β)-induced expressions of type I collagen and fibronectin in 3T3 fibroblast cells. Collectively, culture supernatant of P-Epi has preventive effects on PF, thus cell therapy is not necessarily required.

Despite the several patient-level and healthcare system benefits of peritoneal dialysis (PD) compared to in-centre haemodialysis, the growth in PD utilisation has been limited. This is related to several factors, including deficiencies in modality education for chronic kidney disease patients, nephrology training and governmental policies advocating for this dialysis modality.
