Expression of ECM components along 9 consecutive cell passages of TMJF.

Each gene has been classified as ECM-F (ECM- fibrillar component), ECM-GAGS (ECM-glycosaminoglycans), ECM-MGPS (ECM- multiadhesive gluproteins), ECM-OG (other genes with a function in ECM), ECM-PGS (ECM-proteoglycans). The correlation between gene expression and cell passaging as determined by the Pearson (r) correlation test is shown in the last column. All genes with a positive correlation with cell passaging (r >0.700) are shown with asterisks (*). Genes with a negative correlation with cell passaging (r
