Abstract
BACKGROUND AND AIM Non-alcoholic steatohepatitis (NASH) can lead to cirrhosis and hepatocellular carcinoma. Currently, lifestyle modification is the only effective treatment. We have shown that human amnion epithelial cells (hAECs) reduce inflammation and fibrosis in toxin-induced liver injury models. We examined the effect of these cells and the soluble factors released by the cells into culture medium (hAEC conditioned medium [hAEC-CM]) in a diet-induced murine NASH model. 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.

Abstract
The amniotic membrane (AM) and amniotic fluid (AF) have a long history of use in surgical and prenatal diagnostic applications, respectively. In addition, the discovery of cell populations in AM and AF which are widely accessible, nontumorigenic and capable of differentiating into a variety of cell types has stimulated a flurry of research aimed at characterizing the cells and evaluating their potential utility in regenerative medicine. While a major focus of research has been the use of amniotic membrane and fluid in tissue engineering and cell replacement, AM- and AF-derived cells may also have capabilities in protecting and stimulating the repair of injured tissues via paracrine actions, and acting as vectors for biodelivery of exogenous factors to treat injury and diseases. Much progress has been made since the discovery of AM and AF cells with stem cell characteristics nearly a decade ago, but there remain a number of problematic issues stemming from the inherent heterogeneity of these cells as well as inconsistencies in isolation and culturing methods which must be addressed to advance the field towards the development of cell-based therapies. Here, we provide an overview of the recent progress and future perspectives in the use of AM- and AF-derived cells for therapeutic applications.

Abstract
Human amnion epithelial cells (hAECs) are a heterologous population positive for stem cell markers; they display multilineage differentiation potential, differentiating into cells of the endoderm (liver, lung epithelium), mesoderm (bone, fat), and ectoderm (neural cells). They have a low immunogenic profile and possess potent immunosuppressive properties. Hence, hAECs may be a valuable source of cells for cell therapy. This unit describes an efficient and effective method of hAEC isolation, culture, and cryopreservation that is animal product-free and in accordance with current guidelines on preparation of cells for clinical use. Cells isolated using this method were characterized after 5 passages by analysis of karyotype, cell cycle distribution, and changes in telomere length. The differentiation potential of hAECs isolated using this animal product-free method was demonstrated by differentiation into lineages of the three primary germ layers and expression of lineage-specific markers analyzed by PCR, immunocytochemistry, and histology.
