The collagenolytic responses of normal rat skin fibroblasts (NRS-F) and rat mammary MTLn3 tumor-derived fibroblasts (Ln3-F) were examined following exposure to rat macrophage (M phi-CM)- and lymphocyte (LYM-CM)-conditioned culture medium and/or tumor cell-conditioned medium. Alveolar, intratumoral, and peritoneal macrophages were prepared from mammary adenocarcinoma-bearing rats, as were the pe...

KFGS (Keratinocyte fibrin glue suspension) and FKFGS (Fibroblast keratinocyte fibrin glue suspension) methods were performed in this study. Materials and Methods: Four healthy adult horses were used in this study (350 ± 117). Fibroblast cells have been separated by explant culture method from neck, keratinocyte cells have been separated by enzyme digestion from lib skin samples and Fibrinogen h...

Objectives- Tendons are integral parts of musculoskeletal system and are subjected to injury. Fibroblast is used in tendon healing, however, there is no proved and reported result regarding concurrent use of allogenic fibroblast with static magnetic field in tendon healing. In addition, there are some studies done on the effect of magnetic fields on tendon healing but the results are antithesis...

introduction: one of the major contributing factors, which may cause failure of endodontic treatment, is the presence of residual microorganisms in the root canal system. for years, most dentists have been using calcium hydroxide (ch) as the intracanal medicament between treatment sessions to eliminate remnant microorganisms. reducing the size of ch particles into nanoparticles enhances the pen...

avulsion is one of the most serious emergencies in dental office. in the event of any problem, the tooth should be stored in a medium that supports the periodontal ligament cell viability. in other clinical situations, preserving media, growth factors and mitogenic products may be useful in repairing the traumatized tissues. it has been previously reported that levodopa (l-dopa) accelerates hea...

IL-13 and IL-4, pleiotropic immune regulatory cytokines, have been shown to mediate similar prominent effects in human fibroblast cell lines. However, molecular mechanisms for their redundant effects are not known. Here, we have investigated the structure of IL-13 receptors (IL-13R) and molecular mechanisms of signal transduction through IL-13 and IL-4 receptors in non-transformed normal skin f...
