given the difficulties in accessing articular cartilage as a source of chondrocytes to be used in fabricating cartilage constructs, alternative sources are required. the present study examined chondrocytes from costal cartilage for their suitability in cartilage tissue engineering. chondrocytes isolated from rat knee and rib hyaline cartilage were separately mixed with alginate and placed in a ...

Chondrocytes are the uniquely resident cells found in all types of cartilage and key to their function is the ability to respond to mechanical loads with changes of metabolic activity. This mechanotransduction property is, in part, mediated through the activity of a range of expressed transmembrane channels; ion channels, gap junction proteins, and porins. Appropriate expression of ion channels...
The culture of chondrocytes is one of the most powerful tool for exploring the intracellular and molecular features of chondrocyte differentiation and activation. However, chondrocytes tend to dedifferentiate to fibroblasts when they are subcultured, which is a major problem. This chapter describes several protocols for culturing chondrocytes of different anatomical origins (articular and costa...
The repair of chondral injuries is a very important problem and a subject of many experimental and clinical studies. Different techniques to induce articular cartilage repair are under investigation. In the present study, we have investigated whether the repair of articular cartilage folowing costal chondrocyte transplantation is donor age-dependent. Transplantation of costal chondrocytes from ...
An attempt to repair articular cartilage defects by costal chondrocytes transplantation was made. A full-thickness defect in the rabbit's femoral patellar groove was artificially made. Cultured costal cartilage chondrocytes were then transplanted into the defects and covered with periosteal flaps. Empty defects were used as the control group. Animals were divided into two groups (five rabbits e...
objective(s): protein kinase c (pkcα) is involved in modulating articular chondrocytes apoptosis induced by nitric oxide (no). hyaluronic acid (ha) inhibits nitric oxide-induced apoptosis of articular chondrocytes by protecting pkcα, but the mechanism remains unclear. the present study was performed to investigate the effects and mechanisms of pkcα regulate protective effect of hyaluronic acid....
Generating neocartilage with suitable mechanical integrity from a cell source that can circumvent chondrocyte scarcity is indispensable for articular cartilage regeneration strategies. Costal chondrocytes of the rib eliminate donor site morbidity in the articular joint, but it remains unclear how neocartilage formed from these cells responds to mechanical loading, especially if the intent is to...
In our experiment, we tried to assess the potential of repair of full-thickness defects in articular cartilages of rabbit femurs. An artificially made, full-thickness defect in the rabbit's femoral patellar groove was created. The defects were divided into six groups. The reparative tissue was evaluated by macroscopic, histological, and immunohistochemical examinations. The reparative tissues i...
