Figure 6

Principal component analysis. Three-D scatter plots constructed from principal component analyses of gene expression data. In the scatter plots the first, second and third principal components were plotted on the x, y and z axis respectively. Red circles represent conjunctival samples (control) whereas yellow circles denote primary pterygial samples. A. Performed on all genes, B-L. Using subsets of Gene Ontology genes corresponding to a biological process or molecular function and J-L. Using subsets of Gene Ontology genes corresponding to specific cellular components. Brackets represent the number of genes in the overall analysis (A) or in subsets (B-L)
