Abstract | BACKGROUND AND AIM: METHODS: C57BL/6J male mice received a Western "fast food diet" for 42 weeks. Group 1 received an intraperitoneal injection of 2 × 106 hAECs at week 34, group 2 received an additional hAEC dose at week 38, and group 3 received thrice weekly hAEC-CM injections intraperitoneal for 8 weeks from week 34. Liver fibrosis area, inflammation, and fibrosis regulators were measured by immunohistochemistry, qPCR, and gelatin zymography. Metabolic parameters were also assessed. RESULTS: Fast food diet-fed mice demonstrated peri-cellular hepatic fibrosis, inflammation, and steatosis typical of NASH. Liver fibrosis area was reduced by 40% in hAEC-treated and hAEC-CM-treated mice. hAEC treatment significantly reduced pSMAD 2/3 signaling and the number of activated hepatic stellate cells and liver macrophages. Matrix metalloproteinase 2 and 9 gene and protein expression were variably affected. hAEC treatment did not alter the NASH activity score or metabolic parameters such as bodyweight, total cholesterol, or glucose tolerance. CONCLUSION: Human amnion epithelial cell and hAEC-CM significantly reduced hepatic inflammation and fibrosis in a diet-induced non-alcoholic fatty liver disease model. Although hAEC and hAEC-CM did not affect the metabolic components of NASH, their therapeutic potential is promising and warrants further investigation.
