the skin is the largest tissue of man with several functions. cosmetics/cosmeceuticals agents always are needed to be evaluated for their detrimental effects on the skin. nowadays, the therapeutic potential of stem cells has and fibroblasts have increased the hope for a successful cell therapy in aesthetic medicine. stem cells are unspecialized cells capable of renewing themselves through cell ...
the ultimate goal of the periodontal treatments is a regeneration of periodontium. recently, laser irradiations are commonly used to improve wound repair. because of many controversies about the effects of laser on soft tissue regeneration, more in vitro studies are still needed. the aim of the present in vitro study was to compare the effects of different doses of er:yag (erbium-doped:yttrium,...
background one of the main challenges in skin flap surgery is tissue ischemia and following necrosis. the present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. methods thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal random-pattern skin ...
objective: different techniques have been suggested for the repair of bone defects at the injured sites. use of biomembranes, or application of plasma rich in growth factor (prgf) at the site of proliferation of osteoblasts are among the suggested techniques. the current study aimed to compare the biocompatibility of human periodontal ligament fibroblasts (hplf) cultured on hypro-sorb f, perica...
background: this study was conducted to evaluate fibroblast co-culture and activin a on in vitro maturation and fertilization of mouse preantral follicles. methods: the ovaries from 12-14-day-old mice were dissected, and 120-150 μm preantral follicles were cultured individually in α-mem as based medium for 12 days. a total number of 456 follicles were cultured in four conditions: (i) base mediu...
introduction: mineral trioxide aggregate is being widely used for root end filling, pulp capping, perforation repair, and other endodontic procedures. recently, a material similar to proroot mineral trioxide aggregate (pmta) was developed in iran named root mineral trioxide aggregate (rmta) with the claim of having the exact result of original mta. the purpose of this study was to compare the a...
dendritic cells (dcs) induce pathogen-specific t cell responses. we comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), pha activated t cells (t cell conditioned medium), and mixture of fibroblast & pha activated t cells (fcm-tccm) conditioned media on maturation of dcs. monocytes were cultured with gm-csf and il-4 for five da...
cytotoxicity of depleted uranium, as a byproduct of military has been came to spotlight in recent decades. du is known as a chemical rather than radioactive hazard and efforts to illustrating its mechanism is undergo, but the precise complete molecular mechanisms are still unclear. recent studies showed that uranium induces biological changes in many different target tissues, such as the kidney...
in order to adapt lasota strain of newcastle disease virus (ndv) on chick embryo fibroblast (cef) cells, 0.1 ml from lasota vaccine produced in razi vaccine and serum research institute inoculated to the cef cells and was passaged five times in the cef grown in eagle’s minimum essential medium (mem). first to third passages were blind but in fourth passage cytopathic effect of virus was observe...
fibroblasts could be considered as connective tissue cells that are morphologically heterogeneous with diverse functions depending on their location and activity. these cells play critical role in health and disease such as cancer and wound by production of collagen, fibronectin, cytokines and growth factors. absence of insulin and other growth factors in serum deprivation condition and similar...
