Principal component analysis (PCA) diagram of the 23 selected genes.

<p>A/upon SCF treatment or B/with imatinib treatment. PCA of mRNA selected genes in NIH3T3-infected cell lines as a tool to determine their capabilities to distinguish the different cell lines (WT, wild-type <i>KIT</i>; D6, D6 <i>KIT</i>; D54, D54 <i>KIT</i>; WT/D6, WT <i>KIT</i> and D6 <i>KIT</i>; WT/D54, WT <i>KIT</i> and D54 <i>KIT</i>).
