Gene expression in scleroderma skin biopsies. (A) The dendrogram representing four scleroderma (SSc) subjects is colored red, and the dendrogram for the four normal (nor) control subjects has been colored black. Samples taken from affected forearm (FA) or unaffected back (B) of SSc subjects and normal control subjects are indicated. (B) Overview of gene expression patterns indicating the select clusters of genes shown in more detail. (C) Normal cluster. (D) Collagen I cluster. (E) B lymphocyte cluster. (F) Cell adhesion and extracellular matrix. (G) Smooth muscle cluster. (H) T cell cluster.
