چکیده
TYPE: Abstract TOPIC: Obstructive Lung Diseases PURPOSE: To investigate the protective roles of adipose-derived stem cells-derived exosomes (ADSCs-Exo) in cigarette smoke (CS)-induced COPD and explore underlying mechanism by discovering effects ADSCs-Exo on alveolar macrophages (AMs) pyroptosis. METHODS: ADSCs were isolated from human adipose tissues, then isolated. 24 8-week-old male C57/BL6 mice exposed to CS for 4 weeks, followed intratracheal administration or PBS. MH-S cells, derived mouse AMs, stimulated 2% extract hours, PBS treatment. Pulmonary inflammation was analyzed detecting pro-inflammatory cells mediators bronchoalveolar lavage fluid. histology assessed HE staining. Mucus production determined PAS The profile AMs pyroptosis evaluated levels pyroptosis-indicated proteins. inflammatory response phagocytic activity investigated. RESULTS: In with CS-induced COPD, significantly increased, mucus markedly increased lung architecture obviously disrupted. elevated phagocytosis inhibited. However, greatly reversed these alterations caused exposure. Consistently, extract-induced cellular elevated, pyroptotic upregulated while decreased. Nonetheless, abnormalities remarkably alleviated treatment ADSCs-Exo. CONCLUSIONS: attenuates airway overproduction, injury inhibiting CLINICAL IMPLICATIONS: may be a promising cell-free therapeutic candidate COPD. DISCLOSURE: Nothing declare. KEYWORD: Chronic obstructive pulmonary disease

Induced Pluripotent Stem Cells-Derived Mesenchymal Stem Cells Attenuate Cigarette Smoke-Induced Cardiac Remodeling and Dysfunction
The strong relationship between cigarette smoking and cardiovascular disease (CVD) has been well-documented, but the mechanisms by which smoking increases CVD risk appear to be multifactorial and incompletely understood. Mesenchymal stem cells (MSCs) are regarded as an important candidate for cell-based therapy in CVD. We hypothesized that MSCs derived from induced pluripotent stem cell (iPSC-M...

Objective(s):Bone marrow-derived mesenchymal stem cells (BMSCs) have attracted significant interest to treat asthma and its complication. In this study, the effects of BMSCs on lung pathology and inflammation in an ovalbumin-induced asthma model in mouse were examined. Materials and Methods:BALB/c mice were divided into three groups: control group (animals were not sensitized), asthma group (an...

Adipose-derived stem cells attenuate pulmonary microvascular hyperpermeability after smoke inhalation
BACKGROUND Pulmonary edema is a hallmark of acute respiratory distress syndrome (ARDS). Smoke inhalation causes ARDS, thus significantly increasing the mortality of burn patients. Adipose-derived stem cells (ASCs) exert potent anti-inflammatory properties. The goal of the present study was to test the safety and ecfficacy of ASCs, in a well-characterized clinically relevant ovine model of ARDS....
