Abstract The transcription factor SOX9 is important in maintaining the chondrocyte phenotype. To identify novel genes regulated by SOX9 we investigated changes in gene expression by microarray analysis following retroviral transduction with SOX9 of a human chondrocytic cell line SW1353 . From the results the expression of a group of genes SRPX S100A1 APOD RGC32 CRTL1 MYBPH CRLF1 and SPINT1 was evaluated further in human articular chondrocytes HACs . First the same genes were investigated in primary cultures of HACs following SOX9 transduction and four were found to be similarly regulated SRPX APOD CRTL1 and S100A1 . Second during dedifferentiation of HACs by passage in monolayer cell culture during which the expression of SOX9 progressively .
