In this study, milk was evaluated as a potential storage medium for avu]sed teeth. In various experiments, storage in milk was compared to storage in saliva, in water, and to air drying. The results demonstrate that milk is significantly superior to saliva, water, and air in preserving periodontal ligament fibroblast viability. Based on these results, it is recommended that when an avulsed toot...

Transforming growth factor B (TGF-~), a multifunctional cytokine, is an indirect mitogen for human fibroblasts through platelet-derived growth factor (PDGF), particularly the A ligand-c~ receptor arm of that system. TGF-~ effects on PDGF ot receptor expression were studied in vitro using ligand binding techniques in three human dermal fibroblast strains: newborn foreskin, adult skin, and sclero...

Current models used in our laboratory to assess the migration and traction of a population of cells within biopolymer gels are extended to investigate temporal changes in these parameters during compaction of mechanically constrained gels. The random cell migration coefficient, micro (t) is calculated using a windowing technique by regressing the mean-squared displacement of cells tracked at hi...

Transforming growth factor beta (TGF-beta), a multifunctional cytokine, is an indirect mitogen for human fibroblasts through platelet-derived growth factor (PDGF), particularly the A ligand-alpha receptor arm of that system. TGF-beta effects on PDGF alpha receptor expression were studied in vitro using ligand binding techniques in three human dermal fibroblast strains: newborn foreskin, adult s...

Background: Fibroblast cell lines have different application in biological research including nuclear transfer in cloning, feeder layer of embryonic stem cells, wound healing research and tissue engineering. The objective of the present study was to determine the proper pregnancy age for collecting and culturing guinea pig fetal fibroblast. Materials and Methods: Guinea pig fetuses were collect...

This review discusses the increasing potential of chitosan nanocomposites as viable materials capable targeting these debilitating factors. focuses on various techniques used to process and their mechanical properties. Chitosan are regarded highly effective antimicrobials for treatment chronic wounds. nanocomposites, such chitosan/polyethylene oxide/silica/ciprofloxacin, demonstrate efficient a...

Two consecutive prefractionated fractions of the Australian marine sponge extract, Pipestela candelabra, were identified to be selectively active on the human prostate cancer cells (PC3) compared to the human neonatal foreskin fibroblast non-cancer cells (NFF). Twelve secondary metabolites were isolated in which four compounds are new small peptides. Their structures were characterized by spect...

The genomes of HCMV clinical strains (e.g. FIX, TR, PH, etc) contain a 15 kb region that encodes 20 putative ORFs. The region, termed ULb', is lost after serial passage of virus in human foreskin fibroblast (HFF) cell culture. Compared to clinical strains, laboratory strains replicate faster and to higher titers of infectious virus. We made recombinant viruses with 22, 14, or 7 ORFs deleted fro...
