conclusions a fusion tag from the pet32 expression plasmid permits the recovery of the recombinant fusion fgf-2 from e. coli, without affecting its biological activity. objectives the objective of this study was to overexpress and purify the high-level active human bfgf in escherichia coli (e. coli). materials and methods this experimental study was conducted in the islamic republic of iran. af...

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 ...

wounds and wound healing have always been one of the most important subjects that experimental researches were dedicated to. simvastatin has been used for long as a common lipid lowering agent which was reported to have some pleiotropic effects such as antioxidation, anti-inflammation and immunomodulation. in this study we aimed to determine the effect of simvastatin on wound healing process in...

Lung fibroblasts play a key role in postnatal lung development, namely, the formation of the alveolar gas exchange units, through the process of secondary septation. Although evidence initially highlighted roles for fibroblasts in the production and remodeling of the lung extracellular matrix, more recent studies have described the presence of different fibroblast subsets in the developing lung...

Srinivasan, Suseela, Jennifer Strange, Feyisola Awonusonu, and Margaret C. Bruce. Insulin-like growth factor I receptor is downregulated after alveolarization in an apoptotic fibroblast subset. Am J Physiol Lung Cell Mol Physiol 282: L457–L467, 2002; 10.1152/ajplung.00050. 2001.—After alveolar formation, 20% of interstitial lung fibroblasts undergo apoptosis, a process that is of critical impor...

Transforming growth factor-beta (TGF beta) stimulated the production of total protein, collagen, and fibronectin by normal human lung fibroblasts. The stimulatory response was maximal at 100 pM TGF beta and reversed toward control at higher concentrations. Inhibition of fibroblast prostaglandin (PG) synthesis enhanced TGF beta-induced stimulation of total protein, collagen, and fibronectin prod...
