UNLABELLED Periodontal ligament mesenchymal stem cells (PDLMSCs) are an important alternative source of adult stem cells and may be applied for periodontal tissue regeneration, neuroregenerative medicine, and heart valve tissue engineering. However, little is known about the impact of bacterial toxins on the biological properties of PDLSMSCs, including self-renewal, differentiation, and synthes...
زمینه و هدف: هدف از مطالعه حاضر بررسی مقایسه ای بیان ایمونوهیستوشیمیایی bcl2 و CD105 در کیست رادیکولار، کیست دنتیژروس، ادنتوژنیک کراتوسیست و آملوبلاستوما میباشد. مواد و روش کار: تحقیق حاضر یک مطالعه توصیفی- تحلیلی به روش مقطعی است. تعداد 50 نمونه وارد مطالعه شدند. درصد سلولهای رنگ گرفته با آنتی بادی bcl2 در درشتنمایی 40 در 15 کیست رادیکولار، 15 کیست دنتیژروس، 15 ادنتوژنیک کراتوسیست و 5 آملو...
The present study was designed in order to explore the association between the early metastasis of renal cell carcinoma (RCC) and biological markers of tumor cells. A total of 200 patients with RCC, who received a nephrectomy between January 2015 and October 2015, were enrolled in the present study, while 100 healthy patients served as controls. The expression of cytokeratin 19 (CK19), endoglin...
The present study aimed to observe and compare the values of microvessel density (MVD), mast cell microdensity (McMD) and macrophage microdensity (MphMD) in intratumoral areas compared with the advancing edges, and to assess any correlations between these values and the degree and stage of the neoplasia. The cases of 52 patients who were diagnosed with endometrial carcinoma between 2003 and 201...
Adipose tissue-derived stromal cells, termed ASCs, play an important role in regenerative applications. They resemble mesenchymal stem cells owing to their inexhaustibility, general differentiation potential, and plasticity and display a series of cell-specific and cluster-of-differentiation (CD) marker profiles similar to those of other somatic stem cells. Variations in phenotypes or different...
OBJECTIVE To demonstrate the role of angiogenesis in the progression of cutaneous squamous cell carcinoma. INTRODUCTION Angiogenesis is a pivotal phenomenon in carcinogenesis. Its time course in cutaneous squamous cell carcinoma has not yet been fully established. METHODS We studied the vascular bed in 29 solar keratoses, 30 superficially invasive squamous cell carcinomas and 30 invasive sq...
Current clinical protocols used for isolation and purification of mesenchymal stem cells (MSC) are based on long-term cultures starting with bone marrow (BM) mononuclear cells. Using a commercially available immunoselection kit for enrichment of MSC, we investigated whether culture of enriched BM-CD105(+) cells could provide an adequate number of pure MSC in a short time for clinical use in the...
مقدمه:cd105 یک گلیکوپروتئین غشایی همودیمریک است که در رگسازی جدید نقش دارد. snail2 یک فاکتور رونویسی بوده و منجر به اختلال در چسبندگی اپیتلیالی میگردد. هدف مطالعه حاضر ارزیابی بیان cd105 و snail2 در اپیتلیوم دیسپلاستیک و کارسینوم سلول سنگفرشی دهان بود. مواد و روشها: در این مطالعه توصیفی-تحلیلی، جمعاً 40 بلوک پارافینه کارسینوم سلول سنگفرشی و اپیتلیوم دیسپلاستیک با نشانگر cd105 و snail2 به ر...
PURPOSE The interaction between tumor cells, stroma, and endothelial cells is important for the dissemination of tumor cells. The aim of the present study is to examine vascularity in primary breast carcinomas and its prognostic significance and relationship with tumor cell dissemination. EXPERIMENTAL DESIGN A total of 498 invasive breast carcinomas were analyzed. Representative tumor section...
