Background: The destruction of articular cartilage is the major cause of articular problems. The articular cartilage has little repair postertial due to lack of perichondrium and direct blood circulation. It is, therefore important to consider this phenomena in surgical treatments. One of the articular cartilage reconstructive surgeries is using Osteo-Chondral graft. The main purpose of this re...
We have successfully fabricated the cartilage/natural rubber latex (NRL) biocomposites via human mesenchymal stem cells (hMSCs) spheroid under hypoxic condition. It was revealed that NRL nanoparticles acted as main component, providing surface heterogeneity for spheroids and resulting in a mechanically stable structure with modulus two times higher compared to controls. The formation of cartila...
Objective Articular cartilage as an avascular skeletal tissue possesses limited capacity to heal. On the other hand, it is believed that the regeneration capacity of each tissue is largely related to its stem cell contents. Little is known about the presence of mesenchymal stem cells in articular cartilage tissue. This subject is investigated in the present study. Materials and Methods Artic...
Antibodies directed against whole bovine nasal-cartilage proteoglycan and against the hyaluronic acid-binding region and chondroitin sulphate peptides from the same molecule were used in immunodiffusion and immunoelectromigration experiments. Proteoglycans from bovine nasal and tracheal cartilage showed immunological identity, with all three antisera. Proteoglycans from pig hip articular cartil...
The restoration of the degenerated articular cartilage in patients with osteoarthritis (OA) is still a challenge for researchers and clinicians. Drug interventions and surgical treatments have been widely attempted for cartilage regeneration in OA. However, the results were largely unsatisfactory. Autologous chondrocyte implantation (ACI) or matrix-induced autologous chondrocyte implantation (M...
The purpose of this study was to determine whether delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) and T2 mapping are accurate techniques for measuring cartilage thickness in the metacarpus3/metatarsus3 (Mc3/Mt3) of Thoroughbred racehorses. Twenty-four Mc3/Mt3 cadaver specimens were acquired from six healthy racehorses. Cartilage thickness was measured from postint...
Adult human articular cartilage has been maintained in organ culture for 8 days, and the culture medium, which was changed on alternate days, was pooled. Normal and rheumatoid cartilage was obtained from patients and 4 types of culture were prepared: (1) cartilage alone; (2) cartilage + D-penicillamine; (3) cartilage + homologous synovium; (4) cartilage, synovium, and D-penicillamine. The hexos...
Introduction. Microtia presents a congenital ear deformity ranging from minor and barely visible defect to complete absence of the ear. Currently, there are three options for reconstruction: autologous costal cartilage, silicon prothesis prosthetic Ear reconstruction with cartilage is usually performed in two stages. During first stage cartilaginous framework fabricated placed under skin, anato...
OBJECTIVE The purpose of this study was to perform a quantitative evaluation of the effect of static magnetic field orientation on cartilage transverse (T2) relaxation time in the intact living joint and to determine the magnitude of the magic angle effect on in vivo femoral cartilage. MATERIALS AND METHODS Quantitative T2 maps of the femoral-tibial joint were obtained in eight asymptomatic m...
The friction and wear properties of silica/poly(tetrahydrofuran)/poly(?-caprolactone) (SiO2/PTHF/PCL-diCOOH) hybrid materials that are proposed as cartilage tissue engineering were investigated against living articular cartilage. A testing rig was designed to allow fresh bovine force compared for five compositions the biomaterial articulating freshly harvested in diluted calf serum. Under a non...
