Adipose-derived stem cells (ADSCs) are a heterogeneous cell population that may be enriched by positive selection with antibodies against the low-affinity nerve growth factor receptor (LNGFR or CD271), yielding a selective cell universe with higher proliferation and differentiation potential. This paper addresses the need for determining the quantity of ADSCs positive for the CD271 receptor and...

UNLABELLED In the recent past there has been an increased emphasis on morphogenetic tissue research of periodontal tissues. The aim of this study was to find qualitative and quantitative correlations in distribution and appearance of growth factors/cytokines/defensins and apoptosis in periodontal pathologies. MATERIAL AND METHODS Tissue was obtained from 5 controls and 6 chronical periodontit...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...

Following peripheral nerve injury, Schwann cells undergo a series of cellular alterations that are thought to assist the regenerative process. Some of these changes are stimulated by the local release of cytokines and mitogenic factors. To test the hypothesis that cytokine regulation of gap junctional communication between cells helps to coordinate Schwann cell responses, cultured rat Schwann c...

The nervous system is now recognized to be a relevant component of the tumor microenvironment. Receptors for neuropeptides and neurotransmitters have been identified in breast cancer. However, very little is known about the role of neurogenes in regulating breast cancer progression. Our purpose was to identify neurogenes associated with breast cancer tumorigenesis with a potential to be used as...

There is growing evidence that nerve growth factor (NGF) may function as a mediator of persistent pain states. We have identified a novel nonpeptidic molecule, ALE-0540, that inhibits the binding of NGF to tyrosine kinase (Trk) A or both p75 and TrkA (IC50 5.88 +/- 1. 87 microM, 3.72 +/- 1.3 microM, respectively), as well as signal transduction and biological responses mediated by TrkA receptor...

Background: Complex regional pain syndrome (CRPS) is a rare painful condition that usually appears after trauma or surgery of the extremities. Symptoms include pain, sensory, sudomotor and vasomotor disturbances, trophic changes impaired motor function. The course varies from mild to chronic disease with high impact on daily functioning quality life. In skin tissue, sustained inflammatory, fibr...

Increasing evidence suggests that the nervous system is involved in allergic inflammation. One of the potential regulatory molecules of the neuroimmune system is nerve growth factor (NGF). Recent studies from our group demonstrated the presence of a functional NGF receptor (NGFR) on human B lymphocytes. Moreover, we showed that gp140trk tyrosine kinase, which serves as an NGFR, was involved in ...
