Gene expression clustering of nonhuman primate embryonic stem cell lines. Nine lines were analyzed for gene expression using Affymetrix monkey gene expression chips. Each analysis was performed in triplicate except for nhp206, which was duplicated. Cluster analysis of the average value across the replicates showed striking similarity across all lines with similarity >95% among all lines. However, within that small variation not only did the full siblings cluster together but the lines also clustered according to their sex (females: circles; males: squares).
