Biosynthesis of an interstitial type of collagen by cloned human gastric carcinoma cells.
In an attempt to elucidate the role played by neoplastic epithelial cells in the formation of stromal collagen, the synthesis of collagen by two cloned human gastric carcinoma cell lines was studied. The presence of antigenicity of procollagen alpha 1(I) chain in the cytoplasms of both carcinoma cell lines growing in culture was demonstrated by an immunocytochemical technique using specific ant...
متن کاملIn vitro Comparison of Viability of Human Gingival Fibroblast Cells on Collagen Barriers
Background and purpose: Human gingival fibroblasts cultured on collagen membrane is an alternative treatment method in guided regeneration. This in vitro study aimed at evaluating and comparing the human gingival fibroblasts viability on two types of collagen-rich membranes. Materials and methods: Human gingival fibroblast cells (HGF1-RT1) were cultured on two types of collagen-rich membranes...
متن کاملBiosynthesis of type IV collagen by cultured rat Schwann cells
We have obtained evidence that rat Schwann cells synthesize and secrete type IV procollagen. Metabolic labeling of primary cultures of Schwann cells plus neurons and analysis by SDS PAGE revealed the presence of a closely spaced pair of polypeptides in the medium of these cultures that (a) were susceptible to digestion by purified bacterial collagenase, (b) co-migrated with type IV procollagen ...
متن کاملThe potential of human-derived periodontal ligament stem cells to osteogenic differentiation: An In vitro investigation
Background: Periodontal ligament stem cells (PDLSCs) are considered as a type of mesenchymal stem cell that is beneficial target for numerous clinical applications in periodontal tissue regeneration therapy. Materials and Methods: This study examined the effects of dexamethasone (Dex) on human PDLSCs in vitro. PDLSCs obtained from the roots of patient’s teeth were cultured with Dex (0....
متن کاملCytotoxicity of Silver Nanoparticles on Human Gingival Epithelial Cells: An In-Vitro Study
Objective: Nanosilver has numerous applications in medicine due to its potent antibacterial activity. However, data regarding the bio-safety of its effective concentrations is scarce. This study aims to assess the toxicity of silver nanoparticles on human gingival epithelial cells under in-vitro conditions. Methods: This in vitro study evaluated the toxic effects of filtered and unfiltered ...
