FIG. 1.

Global gene expression profiling of cen3tel cells at different stages of transformation. (A) Dendrogram obtained from unsupervised hierarchical clustering using Euclidean distance as similarity metrics and complete linkage as linkage method. Each branch of the dendrogram is represented by the global gene expression profile of cells at each PD. The vertical axis indicates the Euclidean distance between samples/clusters. (B) Histogram plot showing the number of genes up- or downregulated in cen3tel cells at different PDs relatively to parental fibroblasts.
