Figure Lengend Snippet: GF supports or enhances gene expression levels. The effect of fibronectin, GF, and fibronectin in combination with GF on ATDC5 cell gene expression was investigated. Correlation analysis of relative expression levels was carried out to detect differential gene expression as a function of the cell culture substrate. The mRNA levels were compared for cells seeded on four distinct surfaces. Data points above the diagonal line indicate genes that are upregulated and data points below the diagonal line indicate genes that are downregulated. Data points falling on the diagonal line are not differentially expressed in experimental compared to control conditions. The effect of GF on gene expression is demonstrated in panels A and B. The effect of fibronectin on gene expression is demonstrated in panels C and D. (A) Relative gene expression levels in 2D cell culture conditions compared to cells grown in 3D on GF in the absence of fibronectin. (B) Relative gene expression levels in 2D cell culture conditions compared to cells grown in 3D on GF in the presence of fibronectin. (C) Relative gene expression levels in 2D cell culture conditions comparing the presence and absence of fibronectin. (D) Relative gene expression levels by cells grown in 3D on GF comparing the presence and absence of fibronectin. Genes for which expression levels met or exceeded the control are indicated in magenta, while those genes that were supported by substrate conditions are indicated by turquoise. Col2a1, a marker for chondrocyte differentiation, is shown as a diamond shape and bolded in each frame. Col2a1 is found above the diagonal line in A and B indicating upregulation as a function of 3D GF culture, and below the line in C and D, indicating downregulation as a function of fibronectin in either 2D or 3D culture. Genes included in this analysis are listed in Tables – .
