سلول های بنیادی اسپرماتوگونی (Spermatogonial Stem Cells) یا SSC ها جمعیتی از سلول های بنیادی هستند که با ایجاد اسپرم در تمام طول زندگی مردان قادر به حفظ تولید مثل می باشند. در پستانداران غیر پریمات، این سلول های بنیادی به ترتیب A-single(As)، A-paired(Apr) و A-aligloed(Aal) نامیده می شوند که پیش ساز های سلول های اسپرماتوگونیهستند. در انسان به علت محدودیت مطالعات روی سلول های (SSC)یافته های اندکی...
زمینه مطالعه: در بالغین، سلولهای بنیادی اسپرماتوگونی (SSCs) تنها سلولهای بنیادی هستند که قادر به انتقال اطلاعات ژنتیکی به نسل بعد می‌باشند. با در نظر گرفتن این که یک SSC منفرد می‌تواند به تعداد زیادی از اسپرماتوزوآ تبدیل شود، دستکاری ژنتیکی این سلول‌ها یک تکنولوژی نوین با کاربردهای عملی در گونه‌های مختلف حیوانی را مهیا می‌سازد. هدف: در این مطالعه ارزیابی انتقال ژن (EGFP)رEnhanced Green Fluore...
background: spermatogonial stem cells (sscs) are infrequentself-renewing cells among the type a spermatogoniawithin the seminiferous tubules and are the basis of spermatogenesisin mammalian testis. an adequate number of sscs is aprimary requirement for the study of their behavior, regulation, andfurther biomanipulation. objectives: in this paper, we studiedthe development of the primary co-cult...

Systemic sclerosis (SSc) is a chronic autoimmune disease, featuring fibrosis in multiple organs. The serum from SSc patients contain inflammatory mediators, contributing to SSc pathogenesis and could be used to develop cell culture models. Here, we compared the fibrotic effects of serum samples from SSc patients with TGFβ1 on human dermal fibroblasts (HDFs). HDF cells were cultured in four diff...
OBJECTIVE Maternal skin-to-skin contact (M-SSC) has been found to reduce adverse consequences of prematurity, however, its neurobiological mechanisms have been unknown. The purpose of the study was to examine oxytocin mechanism in modulating parental stress and anxiety during M-SSC and P-SSC (paternal SSC) with their pre-term infants. METHODS Twenty-eight stable pre-term infants and their par...
Spectral Reflectance of suspended sediment concentration (SSC) remotely sensed by satellite images is an alternative and economically efficient method to measure SSC in inland waters such as rivers and lakes, coastal waters, and oceans. This paper retrieved SSC from satellite remote sensing imagery using radial basis function networks (RBF). In-situ measurement of SSC, water flow data, as well ...
OBJECTIVES To determine if anti-cyclic citrullinated peptide (anti-CCP) antibody titers can distinguish the overlap syndrome of systemic sclerosis and rheumatoid arthritis (SSc-RA) in patients with systemic sclerosis (SSc) and to investigate the clinical significance of anti-CCP antibodies in SSc. METHODS Serum levels of anti-CCP antibodies were measured by enzyme-linked immunosorbent assay i...
Systemic sclerosis (SSc) is a complex disease involving multiple genetic factors. A recent genome-wide association study (GWAS) indicated that CD247 was strongly associated with SSc, which was subsequently confirmed in a SSc cohort of European population. However, genetic heterogeneity in different ethnic populations may significantly impact the complex trait of SSc. The studies herein aimed to...
