Abstract (original English)
Hepatic fibrosis, ultimately causing hepatic sclerosis, remains significant health concerns. Adipose-derived mesenchymal stem cell (ADMSC)-derived exosomes (Exo) exhibit amelioration of liver injury. Hepatocyte growth factor (HGF) regulates hepatocyte growthn. However, its involvement during hepatic fibrosis remains unclear. Isolation of ADMSCs and Exo, transfection of HGF overexpression, and activation of hepatic stellate cells (HSCs) by Angiotensin II (AngII) were conducted. Cells were randomized into HSC, AngII-HSC, ADMSCs-Exo, ADMSCs blank -Exo, and ADMSCs HGF -Exo, DPI, LY294002, and SB203580 groups. MTT for cell viability, cell migration, and flow cytometry for ROS were performed. BALB/c mice were treated with CCL4 for hepatic fibrosis models. The mice were randomized into Control, PBS, ADMSCs-Exo, ADMSCs blank -Exo, and ADMSCs HGF -Exo groups (n=6). HE, Sirius red, and Oil Red O staining, liver function indicators, and ELISA for oxidative stress were performed. ROS generation-related and PI3K/Akt/P38MAPK-related factors were detected by immunofluorescence, immunohistochemistry, and western blot. After identification of ADMSC-Exo and transfection, AngII increased cell viability, migration, Collagen I (CoLI), α-smooth muscle actin (α-SMA), ROS, NADPH oxidase 4 (NOX4), PI3K, p-Akt, p-P38MAPK, ras-related C3 botulinum toxin substrate 1 (RAC1), p47 phox , and p22 phox express
