Bone marrow (BM) is the major reservoir for endothelial progenitor cells (EPCs). Postnatal neovascularization depends on not only angiogenesis but also vasculogenesis, which is mediated through mobilization of EPCs from BM and their recruitment to the ischemic sites. Reactive oxygen species (ROS) derived from Nox2-based NADPH oxidase play an important role in postnatal neovascularization; howev...
AIMS Parathyroid hormone (PTH) has been shown to promote stem cell mobilization into peripheral blood. Moreover, PTH treatment after myocardial infarction (MI) improved survival and myocardial function associated with enhanced homing of bone marrow-derived stem cells (BMCs). To unravel the molecular mechanisms of PTH-mediated stem cell trafficking, we analysed wild-type (wt) and green fluoresce...
Although intracoronary administration of bone marrow–derived mononuclear progenitor cells (BMCs) may be associated with improved cardiac function in patients with chronic postinfarction heart failure, the impact on prognosis and clinical outcome of these patients is unknown. To identify potential predictors for a favorable clinical outcome, we assessed natriuretic peptide serum levels as object...
Activation and reprogramming of hematopoietic stem/progenitor cells play a critical role in the granulopoietic response to bacterial infection. Our current study determined the significance of Sonic hedgehog (SHH) signaling in the regulation of hematopoietic precursor cell activity during the host defense response to systemic bacterial infection. Bacteremia was induced in male Balb/c mice via i...

PURPOSE During radiotherapy for head and neck cancer, co-irradiation (IR) of salivary glands results in acute and often lifelong hyposalivation. Recently, we showed that bone marrow-derived cells (BMC) can partially facilitate postradiation regeneration of the mouse submandibular gland. In this study, we investigate whether optimized mobilization of BMCs can further facilitate regeneration of r...
آسیای کارخانه ی طلای زرمهر یک آسیای گلوله ای تر با طول ??? و قطر ??? متر است. در این تحقیق با مدل سازی این آسیای گلوله ای سعی بر آن شده تا با شبیه سازی درست و دقیق و تعیین پارامترهای آسیا به مدلی دقیق از آن دست پیدا کرد تا اگر در آینده نیاز به افزایش یا تغییر در خوراک آسیا بود بتوان بدون نیاز به کار تجربی و توقف آسیا و کارخانه، با توجه به مدل آسیا تغییرات به وجود آمده در خوراک را بررسی کرد. همچ...
Lipopolysaccharide (LPS) has been shown to induce proliferation of human T-lymphocytes only in the presence of monocytes and CD34(+) hematopoietic cells (HCs) from peripheral blood. This finding provided evidence of an active role of CD34(+) HCs during inflammation and immunological events. To investigate mechanisms by which CD34(+) HCs become activated and exert their immune-modulatory functio...
CONTEXT Clinical trial results suggest that intracoronary delivery of autologous bone marrow mononuclear cells (BMCs) may improve left ventricular (LV) function when administered within the first week following myocardial infarction (MI). However, because a substantial number of patients may not present for early cell delivery, the efficacy of autologous BMC delivery 2 to 3 weeks post-MI warran...
