Integrin mediated cell-extracellular matrix interactions are required for survival and differentiation of many cell types. In this review, the cell-matrix attachment complex (CMAX) is described for chondrocytes. The evidence that integrin-mediated signal transduction is necessary for normal chondrocyte differentiation and survival in various culture conditions and in vivo are reviewed. The poss...
Cartilage tissues possess intrinsic circadian oscillators, which influence chondrocyte function and chondrocyte specific gene expression. However, it is not fully understood how chondrogenesis influences the circadian clock, and vice versa. Thus, we established ATDC5 cells which were stably transfected with the Bmal1:luc reporter and revealed robust circadian rhythms in ATDC5 cells during diffe...
CONTEXT There is insufficient knowledge about the chondrocyte membranome and its molecular composition. OBJECTIVE To develop a Triton X-114 based separation technique using nanoLC-MS/MS combined with shotgun proteomics to identify chondrocyte membrane proteins. MATERIALS AND METHODS Articular chondrocytes from equine metacarpophalangeal joints were separated into hydrophobic and hydrophilic...
Osteoarthritis is a common debilitating joint disorder. Risk factors for osteoarthritis include age, which is associated with thinning of articular cartilage. Here we generate chondrocyte-specific salt-inducible kinase 3 (Sik3) conditional knockout mice that are resistant to osteoarthritis with thickened articular cartilage owing to a larger chondrocyte population. We also identify an edible Pt...
Background: Although the presence of articular cartilage progenitor cells is already known, but due to lack of blood supply, its ability to heal is poor. In past, tissue engineering approaches has been mainly focused on the collection and culture of chondrocyte cells on biodegradable scaffolds such as polyglycolic acid in vitro and their autologous transplantation. Recently, due to the difficul...
Background and purpose: Mesenchymal stem cells (MSCs) are the most widely used cell sources for cartilage tissue engineering. In the present study, human stem cells were used as a cell source. Scaffolds play an important role in tissue engineering, therefore, this study aimed at evaluating the ability of fibrin scaffolds in chondrogenic differentiation of adipose-derived mesenchymal stem cells ...
Introduction: Poly lactic co- glycolic acid (PLGA) and poly caprolacton (PCL) are highly applicable polymers in the field of drug delivery and tissue engineering scaffolds. Therefore, this study aimed to design an insulin-loaded PCL/PLGA hybrid nanofiber scaffold in order to be applied in attachment and growth of chondrocytes. Moreover, it can provide a vehicle for the controlled release of a...
Introduction Articular cartilage is a highly specialized tissue that is vulnerable to injury and disease and has a limited capacity for self-regeneration. The autologous chondrocyte transplantation technique has not been successful because of rapid dedifferentiation of chondrocytes in monolayer culture, producing fibroblast-specific markers (mainly collagen I) rather than a cartilage-specific m...
ELOVL family member 6, elongation of very long chain fatty acids (Elovl6) is a microsomal enzyme, which regulates the elongation of C12-16 saturated and monounsaturated fatty acids. Elovl6 has been shown to be associated with various pathophysiologies including insulin resistance, atherosclerosis, and non-alcoholic steatohepatitis. To investigate a potential role of Elovl6 during bone developme...
