Global microarray analysis of gene expression. (A) Unsupervised three-dimensional representations of principal components 1, 2, and 3 for each microarray for the six donors cultured to passage 7, run in triplicate, for a total of 54 microarrays. Each symbol (circle, diamond, triangle) represents one sample on one microarray containing 35,035 probes. (B) Kernel density plots of normalized data for each of the donor/passage replicates. (C) Box-plot distributions of the technical variability per probe for each donor/passage.
