Variance and sample clustering of normalized transcriptome expression values principal component analysis (PCA) of young MRC-5 (triangles) and HFF (spheres) fibroblast cells of low PDs (MRC-5: 32, HFF: 16) subjected to 0 (control, green) and 20 Gy (blue) irradiation. Triplicates (identical symbol and color) are clustered indicating small experimental errors
