Abetes was induced by intraperitoneal injection of streptozotocin into 8-week-old C57BL/6 male mice. At eight weeks right after the induction of diabetes, the animals were distributed into 7 groups: handle non-diabetic mice and diabetic mice receiving two successive intracavernous injections of HEPES-buffered saline (HBS, days -3 and 0; 20 L) or ESC-JOURNAL OF EXTRACELLULAR VESICLESderived EV-mimetic NVs (ESC-NVs, days -3 and 0; 0.1 g, 0.five g, 1 g, two g, or five g in 20 L of HBS, respectively). Two week just after remedy, we measured erectile function by electrical stimulation from the cavernous nerve. The penis was then harvested for histological and biochemical research. We also examined the effects of ESC-Exo in principal cultured mouse cavernous endothelial cells (MCEC) and pericytes (MCP) in vitro; and in cultured aortic ring and important pelvic ganglion (MPG) ex vivo. Results: Intracavernous injections of ESC-NVs drastically improved erectile function in diabetic mice, which reached as much as 90 of control values. ESC-NVs induced considerable restoration of cavernous contents of endothelial cells, smooth muscle cells, pericytes, and neuronal cells in diabetic situation. Additionally, ESCNVs promoted micro-vascular sprouting from aortic ring and accelerated tube formation in principal cultured MCEC and MCP mono-culture or co-culture system in vitro. Summary/Conclusion: ESC-NVs successfully restored erectile function via enhanced cavernous angiogenesis and neural regeneration in diabetic mice. It will be a far better strategy to use ESC-NVs than ESCs for the treatment of retractable erectile dysfunction despite the fact that it remains to be solved for future clinical application of ESCs.PT12.Human adipose tissue-derived mesenchymal stem cell exosomes for the remedy of liver fibrosis Sol Shin, Soyoung Son, Gyeongtaek Lim, Seunglee Kwon and Jaehyung Parkaof A-exo was determined by BCA assay. The effect of A-Exo on the expression degree of -SMA was evaluated by IF analysis. Mice have been received thioacetamide intraperitoneally. Fluorescently labelled A-exo was administered to mice and whole-body fluorescence was observed in order to evaluate the in vivo distribution. The therapeutic efficacy of A-exo was determined by measuring the amount of ALT, ALP, TBIL and TP in blood of mice. A-exo was 5-HT1 Receptor Inhibitor web injected intravenously 3 times and blood was collected following final injection. Final results: When hepatic stellate cells were activated with TGF-1, the expression level of -SMA was AT1 Receptor Antagonist Synonyms substantially enhanced. Whilst, the level was remarkably decreased based on the treatment concentration of A-Exo. A-exo remedy considerably decreased expression mRNA of pro-fibrogenic marker: -SMA, Collagen I and MMP-2. Just after systemic administration of exosome, a substantial accumulation of A-Exo at liver was observed in each the regular and mice model of liver fibrosis. Furthermore, liver function of A-exo treated group was restored to regular. These results showed A-exo had the high therapeutic efficacy. Summary/Conclusion: Within this study, we investigate the potential of stem cell-derived exosome as the new therapeutic approach for liver fibrosis therapy. Aexo has equivalent bioactive capacity to its origin cell, mesenchymal stem cell. The beneficial effect of A-exo was confirmed in vitro and in vivo tests. The superior therapeutic efficacy was displayed in A-exo treated mouse group.PT12.HucMSC exosome confer protection against ultraviolet radiation induced acute photodamage by means of modulation of SIRT1 pathway Peipei.
