Objective(s): The mesenchymal stem cells (MSCs) have been introduced as appropriate cells for tissue engineering and medical applications. Some studies have shown that topography of materials especially physical surface characteristics and particles size could enhance adhesion and proliferation of osteoblasts. In the present research, we studied the distinction effect of 30 and 60 μg/ml of zinc...
A detailed physicochemical properties of aqueous solutions of alizarin red S - tin (II) chloride, has been thoroughly investigated by extensively exploring the effect of pH, concentration and temperature on the optimal conditions for the formation of tin (II)-alizarin red S (ARS-Sn II) complex. UV-Vis spectra, electrical conductivity and pH method were also used to characterize the final produc...
BACKGROUND Ideally, bone tissue engineering products should have the ability of osteoconduction and osteoinduction. According to the tissue engineering principle, mesenchymal stem cells (MSCs) combined with an appropriate scaffold can be used as a bone substitute for bone defects. Here we used Interpore as a scaffold loaded with MSCs mixed in hydrogel (Pluronic F127). In order to demonstrate th...
PURPOSE To evaluate the functional outcome of tissue-engineered corneal endothelium reconstructed on a devitalized carrier and transplanted in the living feline model. METHODS Eighteen healthy adult cats underwent full-thickness corneal transplantation. In 11 animals, the donor cornea was reconstructed from cultured allogeneic feline corneal endothelial cells seeded on the denuded Descemet's ...
PURPOSE The authors conducted in vivo assessment of corneal endothelial toxicity of air and SF6 in the feline model. This research was motivated by the increased use of air in anterior segment surgery in human subjects. METHODS This was a prospective masked study. The eyes of 16 healthy adult cats were randomly assigned for the injection of 0.7 mL air into the anterior chamber of one eye and ...
To investigate the biocompatibility of the biomaterial, polylactic acid (PLA) with stem cells from human exfoliated deciduous teeth (SHED) and its induction of mineralization as a type of scaffold material. To determine the impacts of biomaterial PLA on proliferation and mineralization of SHED, the expression of surface molecules of SHED isolated and cultured in vitro was detected by flow cytom...
background: in the field of cellular therapy, the impact of confluence degree on harvesting or differentiation of bmmscs and the effect of cell-to-cell contact remain controversial. therefore, the effect of confluence on properties of bmmscs was studied and efficiency of confluence-associated osteogenic differentiation was identified. materials and methods: the impact of 20, 50, 70, 80 and 100%...
The activated charcoal was used for the removal of alizarin red dye from aqueous solution. Different parameters such as effect of contact time, initial dye concentration and pH were investigated. It was observed from the concentration study that the amount of dye adsorbed per unit mass of the adsorbent increased with increase in dye concentration. The pH study presented that the adsorption of d...
