    Notes: Summary Chondrocytes from articular and growth plate cartilage were grown in primary culture. The lipid content, distribution into different types, as well as the fatty acid patterns of these lipids were compared when the cells had reached stationary phase and were synthesizing maximal amounts of proteoglycans. Numerous significant differences were observed, depending on the origin of the chondrocytes. In particular, growth plate chondrocytes showed increased dry weight, increased lipid content (phosphatides and triglycerides), and decreased cholesterol to phosphatide ratio when compared to articular chondrocytes; they also incorporated more of C18:1 and less C16:0 into their major lipid types. Whether these differences arise from specific metabolic regulation or are a consequence of chondrocyte organization in primary culture remains unclear.

    Topics: Biology , Medicine
    Notes: Summary Lapine articular chondrocytes were subcultured in the presence or absence of the prostanoid precursors, arachidonic acid or dihomo-gammalinolenic acid, and the cyclooxygenase inhibitor indomethacin. Lipid storage was studied microscopically using the Sudan black staining method. Control chondrocyte cultures showed a weakly positive staining reaction until confluence was reached, at which point the intra-cytoplasmic lipid content decreased. Both arachidonic acid and dihomo-gamma-linolenic acid at 100 μmol/l caused a marked increase in lipid storage which continued even after confluence was achieved. 1 μmol/l concentrations were indistinguishable from controls, whereas 10 μmol/l concentrations elicited a slight increase in lipid storage compared with controls. The prostaglandin cyclooxygenase inhibitor indomethacin did not affect chondrocyte lipid storage. However, administration of a prostanoid precursor in the presence of indomethacin caused a massive increase in intra-cytoplasmic storage of lipid, eventually leading to cell death. A possible explanation is that indomethacin may alter chondrocyte lipid metabolism in the presence of substrate molecules by rechanneling lipid synthesis away from the prostaglandin pathway to other lipid synthetic pathways.

    Description: The rapid advances in computer and communication technology in the 1970's have enabled large interactive scientific and technical information retrieval systems to be implemented. Major search services today offer on-line access to millions of bibliographic citations and an increasing number of "electronic handbooks." In addition, development of knowledge bases is well under way. Despite the impressive speed and flexibility of interactive retrieval systems, their impact has been lessened by limited awareness of their existence, uneven quality of retrieval, inadequate linkages among data bases, and reliance on specially trained intermediaries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doszkocs, T E -- Rapp, B A -- Schoolman, H M -- New York, N.Y. -- Science. 1980 Apr 4;208(4439):25-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6987735" target="_blank"〉PubMed〈/a〉
