Background: This work aimed to show and compare the degradation time of some of cartilage extracellular matrix components using an in vitro model for cartilage degradation induced by interleukin-1 alpha. It is known that elucidation of molecular events under Interleukin-1 alpha induction of bovine nasal cartilage could obtain useful data to understand more about involving mechanisms for tissue ...
bone has a capability to repair itself when it is fractured. repair involves the generation of intermediatetissues, such as fibrous connective tissue, cartilage and woven bone, before final bone healing can occur. theprocess of cartilage-to-bone transition (cbt) is a key for the achievement of rigid bone healing duringfracture repair. we tested this potential for elastic cartilage using a long ...
the importance of mesenchymal stem cells (mscs), as adult stem cells (ascs) able to divide into a variety of different cells is of utmost importance for stem cell researches. in this study, the ability of cartilage extract to induce differentiation of rat derived omentum tissue mscs (rot-mscs) into chondrocyte cells (ccs) was investigated. after isolation of rot-mscs, they were co-cultured with...
Diced rib cartilage is an acceptable option in severe nasal deformities. We present our preliminary experience in KAMC in nasal septoplasties using the autologous diced costal cartilage. This is a retrospective study of the 22 cases who needed the autologous diced costal cartilage in our centre in 4 years. All our patients needed autologous diced rib cartilages. Twelve were wrapped with tempora...
BACKGROUND Tissue engineering is used for the treatment of many diseases, and the ideal cell source for cartilage tissue engineering is chondrocytes. The main limitation of chondrocyte is the low number of cells in cartilage tissue engineering. This study investigated a suitable cell source with high proliferation rate to obtain a large number of chondrocytes. METHODS Adult cartilage t...
background: integrins are a family of transmembrane proteins that allow communication between the extracellular matrix and the interior of cells. chondrocytes, cells of articular cartilage, express integrins and these molecules appear to have a variety of roles including mechanotransduction. integrins are known to associate with a number of accessory molecules such as cd147 that may act to regu...
Objective- To determine the effect of the transcutaneous electrical neural stimulation on healing of hip joint cartilage defect in rabbit.Design- Experimental in vivo study.Animals- 12 adult New Zealand rabbits were used.Procedures- Under effective the right femoral head was subluxated and the maximum accessible cartilage was denuded up to subchondral bone using dental bit in each rabbit. Then ...
introduction: to demonstrate surgical techniques and to compare the anatomical and functional outcomes between temporalis fascia and cartilage palisade grafting in type-i underlay tympanoplasty in patients with large/subtotal perforation.materials and methods:temporalis fascia and cartilage palisade grafting were conducted in group a and group b, respectively, each containing 30 patients with l...
background filler materials are gaining popularity in nonsurgical rhinoplasty the major advantages are the ability to camouflage the surface deformities, and also the soft and malleable consistency while the major drawback of the safe fillers such as hyaluronic acid is short durability. in this study, we evaluated the injectable cartilage shaving as an autologous filler material for correction ...
articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. the scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. cartilage tissue engineering requires 3 components: cells, scaffold, and environment. owning to their ...
