Objective(s): To improve water stability of electrospun chitosan/ Polyethylene oxide (PEO) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers. Materials and Methods: Different amounts of genipin were added to the chitosan/PEO solutions, chitosan/PEO weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...
The fibroblast growth factor receptor family consists of four receptor tyrosine kinases which bind with varying affinity and specificity to a family of at least fifteen polypeptide ligands. The receptors and ligands perform many essential functions during growth, development and repair. Recent discoveries show that a growing number of skeletal abnormalities result from mutations in the fibrobla...
Cardiac fibroblasts have been long recognized as active participants in heart disease; however, their exact physiological and pathological roles remain elusive, mainly due to the lack of specific markers. In this issue of the JCI, Moore-Morris and colleagues used a fibroblast-specific collagen1a1-GFP reporter to demonstrate that fibroblast accumulation after aortic banding in murine hearts aris...
The multifunctional cytokine p43 acts on endothelial and immune cells to control angiogenesis and inflammation. In this report, we describe an additional activity of p43 that specifically promotes fibroblast proliferation and wound repair. In skin wound regions from mice, tumor necrosis factor-alpha induced p43 expression and secretion from macrophages recruited to the site. p43 also promoted f...
Human normal, periodontitis and overgrown gingival fibroblasts were assayed concerning proinflammatory cytokines secreting ability. Stimulating effect of gingival overgrowth-inducing drugs such as phenytoin, nifedipine or cyclosporine A and LPS on the secretion ability of each fibroblast specimen was also estimated. The supernatant of cultured medium was assayed cytokines by ELISA techniques. I...
objective(s): vascular calcification is one the major characteristics in patients with various types of chronic inflammatory disorders. mirnas have been shown to be involved in many normal biological functions as well as diseases; however, their role in vascular calcification has not received much attention. materials and methods: in the current study, we built a vascular calcification rat mode...
a new strategy for construction of synthetic gene encoding human basic fibroblast growth factor comprising dna annealing-ligation and augmentation by polymerase chain reaction was introduced. the sequence of the gene and corresponding amino acid chain were modified in order to increase stability of the protein. first, 300 bp and 160 bp fragments of the gene were assembled from 18 oligonucleotid...
Bleomycin-induced pulmonary fibrosis in hamsters is associated with collagen accumulation that results from increased lung collagen synthesis rates. However, 1-2 wk after intratracheal instillation of bleomycin, lung collagen synthesis rates decline toward control values. To evaluate the potential role of the bronchoalveolar macrophage in regulating lung collagen production, we studied the effe...
Human fibroblast-like synoviocytes play a vital role in joint synovial inflammation in rheumatoid arthritis (RA). Proinflammatory cytokines induce fibroblast-like synoviocyte activation and dysfunction. The inflammatory mediator Krüppel-like factor 4 is upregulated during inflammation and plays an important role in endothelial and macrophage activation during inflammation. However, the role of ...
