This study has aimed to study different culture systems that might stimulate an increase in cell proliferation of normal and osteoarthritis chondrocytes from articular cartilage in rat model.
Three culture systems using chondrocytes embedded in alginate beads were tested: chondrocytes cultured in Dulbecco's modified Eagle's medium (DMEM) as control, a co-culture system consisting of a monolayer of de-differentiated chondrocytes as a source of mitotic factors, and an enriched medium containing culture medium obtained from a monolayer of chondrocytes and DMEM. Normal and osteoarthritis chondrocytes were stained with 5-carboxyfluorescein diacetate succinimidyl ester and were cultured in each of the three systems.

Although growth factor therapy could be an attractive method for stimulating the repair of damaged cartilage matrix, there is evidence that with aging and/or with the development of osteoarthritis (OA), articular chondrocytes may become unresponsive to growth factor stimulation. The aim of the current study was to compare the ability of insulin-like growth factor+(IGF-1) and osteogenic protein+(OP-1), alone and in combination, to stimulate human normal and OA chondrocytes in culture.
Chondrocytes isolated by enzymatic digestion of cartilage obtained from subjects undergoing knee replacement for OA (n = 6) or from normal ankle joints of tissue donors (n = 7) were cultured in alginate beads in serum-free medium and treated for 21 days with 100 ng/ml IGF-1, 100 ng/ml OP-1, or both.

Small proteoglycans (PGs) are supposed to play great roles in the assembly of cartilage matrix but the influence of cytokines and growth factors on their synthesis by articular chondrocytes is largely unknown. We investigated whether IL-1 and TGFbeta1 influence the production of small leucine-rich proteoglycans by chondrocytes cultured in a three-dimensional gel, as compared to the common monolayer system. Rabbit articular chondrocytes were cultured in alginate beads for 14 days or as monolayers for 7 days.

The endothelin-1 (ET-1) concentrations were measured by RIA in the media of confluent monolayer cultures of rat articular chondrocyte (RAC) exposed to fetal calf serum (FCS) and several growth factors and cytokines. The cells were obtained from 1- and 18-month-old rats. First passage cells were starved in Dulbecco's modified Eagle's medium (DMEM) containing 0.

The purpose of this research was to develop a serum-free culture system for the proliferation of articular chondrocytes. Various growth factors and hormones were tested for their ability to stimulate avian articular chondrocyte proliferation in a defined, serum-free media. Multiple members of the fibroblast growth factor (FGF) family (FGFs: 2, 4, and 9), insulin-like growth factor-1 (IGF-1) and transforming growth factor beta (TGF-beta) significantly stimulated H-thymidine uptake by chondrocytes grown in an adherent serum-free, culture system.
