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,...

The inconsistency of efficiency in murine embryonic stem cell (ESC) production might be associated with the differences in preparation and cryopreservation of the feeder cell layer. As the cryopreservation of mouse embryonic fibroblast (MEF) declined the quality of MEF as feeder cell layer, an effective protocol should be determined to produce murine ESC on frozen-thawed feeder cell layer as ef...

Background: The aldehyde dehydrogenase (ALDH) superfamily composes a group of 20 enzymes that catalyze oxidation. Within this enzyme family, ALDH3A2 stands out for its central role in the oxidation long-chain aldehydes. Of particular interest, substrates include also profibrotic lipid mediators such as sphingosine 1-phosphate or leukotrienes, which have been reported to be deregulated context S...

Accurate regulation of dermal fibroblast function plays a crucial role in wound healing. Many fibrotic diseases are characterized by a failure to conclude normal tissue repair and the persistence of fibroblasts inside lesions. In the present study we demonstrate that endoglin haploinsufficiency promotes fibroblast accumulation during wound healing. Moreover, scars from endoglin-heterozygous (En...

By virtue of their location within blood vessels and their ability to express foreign genes, endothelial cells are attractive vehicles for the delivery of therapeutic molecules in vivo. We wished to determine whether i.v.-injected, genetically modified endothelial cells can become incorporated into sites of active angiogenesis in vivo. To do so, we studied the fate of i.v.-injected, lacZ-expres...

We previously reported that the extract from cuttlebone (CB) has wound healing effect in burned lesion of rat. In present study, the main component of CB extract was analyzed and its wound healing activity was evaluated by using in vitro acute inflammation model. The extract of CB stimulated macrophages to increase the production of TNF-α. The extract also enhanced the production of TGF-β and V...
