We aimed to elucidate the role of the Ca-independent PKC isoenzyme PKCdelta in the regulation of spontaneous in vitro chondrogenesis occurring in a 6-day-long culturing period in chicken limb bud-derived high density cell cultures (HDC). PKCdelta expression and activity were detectable throughout the entire culturing period with a peak on days 2 and 3, when most of the chondroblasts differentia...
OBJECTIVE Mesenchymal stem cells (MSCs) can differentiate into cells of mesenchymal lineages, such as osteoblasts and chondrocytes. Here we investigated the effects of IL-17, a key cytokine in chronic inflammation, on chondrogenic differentiation of human MSCs. METHODS Human bone marrow MSCs were pellet cultured in chondrogenic induction medium containing TGF-β3. Chondrogenic differentiation ...
Proteins of the transforming-growth-factor-β (TGF-β)-superfamily have a remarkable ability to induce cartilage and bone and the crosstalk of TGF-β - and BMP-signalling pathways appears crucial during chondrocyte development. Aim was to assess the regulation of TGF-β-superfamily members and of Smad2/3- and Smad1/5/9-signalling during endochondral in vitro chondrogenesis of mesenchymal stromal ce...
In the present study we have used radiometric thin layer chromatography (TLC) and radioimmunoassay (RIA) to examine the synthesis of various prostaglandins (PGs) during the progressive chondrogenic differentiation limb mesenchymal cells undergo in micromass culture. Throughout the 3-day culture period, [3H]arachidonic acid (AA) is metabolized to compounds which comigrate with authentic PGE2, PG...
Recent studies have demonstrated that adipose-derived mesenchymal cells (AMCs) offer great promise for cell-based therapies because of their ability to differentiate toward bone, cartilage, and fat. Given that cartilage is an avascular tissue and that mesenchymal cells experience hypoxia during prechondrogenic condensation in endochondral ossification, the goal of this study was to understand t...
The in vitro process of chondrogenic differentiation of mesenchymal stem cells for tissue engineering has been shown to require three-dimensional culture along with the addition of differentiation factors to the culture medium. In general, this leads to a phenotype lacking some of the cardinal features of native articular chondrocytes and their extracellular matrix. The factors used vary, but r...
