curcumin is a natural substance with anti-cancerous properties without many disadvantages of currently-used anticancer drugs. its toxicity is significantly higher in tumor cells compared with normal cells. we hypothesized the difference of p53 function between normal and tumor cells as one of the presumable causes of this phenomenon. we knocked down the expression of p53 in normal fibroblasts u...
introduction : the aim of this study was to compare the cytotoxicity of mineral trioxide aggregate (mta) and a new endodontic cement (nec) on l929 mouse fibroblasts. materials and methods: different dilutions (neat, 1/2, 1/10, 1/100) of fresh and set materials placed adjacent flasks of l929 in dmem medium. cellular viability was assessed using mtt assay in three time intervals (24, 48, and 72 h...
objective: in necrotic immature teeth, intra canal medicaments such as triple antibiotic paste (tap) and calcium hydroxide (ch) are used for root canal disinfection and regeneration treatment. however, the effect of these medicaments on dental pulp fibroblasts has yet to be known. this study aimed to assess the cytotoxicity of ch and tap against cultured human dental pulp fibroblasts (hdpfs) ob...
objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine. the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...
Abstract Background and purpose: Delayed wound healing is a common complication of diabetes mellitus. However, less is known about the cause of this pathology. Types of skin cells, extracellular matrix and variety of growth factors are involved in wound healing. The use of recombinant growth factors in researches and production of skin substitutes are still a challenge. Much research has bee...
human diploid fibroblast cells produce a spectrum of necessary growth factors and extracellular matrix (ecm) components essential for growth and proliferation of a variety of other cell types. in this study, the effect of five human embryonic fibroblast cell lines, isolated from liver, lung, skin and foreskin tissues, was investigated. a coculture system analyse was employed to cloning efficien...
plant-based drugs are regarded promising recently. scrophularia has been shown various biological activities such as antimicrobial, antitumor and anti-inflammatory properties. according to pervious researches, bacteria are becoming resistant to some kinds of antibiotics, so it is prominent to find more reliable sources against them. here staphylococcus aureus as a common type of gram- positive ...
background: since embryonic stem (es) cells have the dual ability to proliferate indefinitely and differentiate into multiple tissue types, es cells could potentially provide an unlimited cell supply for human transplantation. objective: in order to study the differentiation of mouse embryonic stem (mes) cells, they were cultured in suspension by using es media without leukemia inhibitory facto...
Galectin-1 and superoxide dismutase are two known molecules in the wound healing process that induce such healing by different mechanisms in the wound site. Larval therapy is one of the methods use by Lucilia sericata fly larvae, nowadays returned to the list of therapeutic methods despite chronic diabetic ulcers and antibiotic resistance of bacteria. In this study, we aimed to evaluat...
