Changes of chondrocyte metabolism in vitro: an approach by proteomic analysis.
Changes in chondrocyte metabolism in vitro using different support systems and under different culture conditions were studied with a proteomic approach. Qualitative and quantitative modifications in the synthesis of chondrocyte proteins were investigated using two-dimensional (2D) gel electrophoresis. This technique provided a simple way to visualize the most abundant chondrocyte proteins. Proteins were identified after in-gel proteolysis with trypsin and matrix-assisted laser desorption ionization-time of flight mass spectrometry, using peptide mass fingerprinting. Tryptic peptide masses were measured and matched against a computer-generated list from the simulated trypsin proteolysis of a protein database (SwissProt).
