Phenotype of chondrocytes in osteoarthritis
Biorheology, 2008Articular cartilage is composed by a unique cell population, the chondrocytes, embedded in an abundant extra-cellular matrix (ECM). Growth, differentiation and homeostasis of the cartilage are regulated by an intricate interplay between the chondrocytes and ECM, which allows the matrix to send signals to the chondrocytes and the chondrocytes to sense ...

Mitochondrial granules in chondrocytes
Calcified Tissue Research, 1969Rat and mice epiphyseal growth plates were studied with the electron microscope. A gradient of mitochondrial electron-dense granules was found. Chondrocytes in the proliferative zone had few granules, while those of the succeeding zones showed a gradual increase in number and density until the zone of provisional calcification was reached.

Journal of Ultrastructure Research, 1967
Electron microscopic investigation of embryonic mouse radii reveals that chondrocytes in epiphyseal cartilage can form single cilia. The cilia can be distinguished from ordinary microvilli by their greater length and the organization of their bases, which are formed by a centriole accompanied by a second one in the near neighborhood.

Autologous chondrocyte transplantation
Operative Techniques in Sports Medicine, 2000Since its introduction in 1987, autologous chondrocyte transplantation (ACT) for the management of full-thickness chondral defects of the knee has gained considerable attention and has renewed interest in cartilage repair. At this time there are patients with 10 to 13 years of follow-up who have continued to benefit from ACT.

AbstractChondrocytes constitute the sole cell type found within cartilage, and control the formation and composition of cartilage. Cellular, biochemical and pharmacological studies of arthritis and other cartilage disorders have increasingly focused on chondrocyte function.

Chondrocytes in Aging Research
1979Publisher Summary Chondrocytes or cells derived from cartilaginous tissues represent a highly differentiated cell type and they synthesize and secrete a unique and specific protein, Type II collagen. Collagen synthesis is studied in a variety of systems utilizing cells derived from different tissues of a number of species. Populations of chondrocytes

The breakdown of collagen by chondrocytes
The Journal of Pathology, 1980The chondrocytes of pure articular cartilage from young pigs display collagenolytic activity when the cartilage is cultivated by an organ culture method in medium containing 5--10 IU retinol/ml. Breakdown of collagen occurs in all regions of the cartilage; in the thicker explants it is greatest and most frequent in those that contain the deepest zone ...

Culture of Immortalized Chondrocytes and Their Use As Models of Chondrocyte Function
2004Immortalization of chondrocytes increases life span and proliferative capacity but does not necessarily stabilize the differentiated phenotype. Expansion of chondrocyte cell lines in continuous monolayer culture may result in the loss of phenotype, particularly if high cell density is not maintained. This chapter describes strategies for maintaining or

AbstractThe objectives of this study were to establish a growth factor response profile for adult human articular chondrocytes, to determine whether this is unique for chondrocytes or influenced by the differentiation status of the cells, and to characterize growth factor interactions.

Transplantation of Isolated Chondrocytes
Clinical Orthopaedics and Related Research, 1991Intramuscular transplantation of isolated syngeneic chondrocytes from hyaline and elastic cartilage results in formation of cartilage with various degrees of similarity to the original tissue. Cells from cartilage with a simple structure, such as nasal septal cartilage, form islands of tissue with flattened chondrocytes at the periphery and more ...
