Figure 1: Hierarchical clustering of microarray data. The dendrogram shows all the 441 genes differentially expressed in ATSC (selected by -test, value 0.01) resulting from the statistical analysis [3]. Each row represents a single gene, while cell types are grouped in columns. The colored representation of gene expression is shown according to the scale on the right side of the figure. BMSC: bone-marrow-derived stromal cells; MRC5: human lung fibroblast cell line. See [3] for details.
