Microarray analysis of EEC subtypes.

(A) Global microarray expression profiles in five EEC subtypes, MIN6 cells, mouse islets and C2C12 cells. (B) Scatter plots and associated correlation coefficients. RMA intensities of individual microarray probes were compared between different cell types and plotted on a log (10) scale. The numbers indicate the correlation coefficients. (C) Dendrogram showing the relationships between different cell types as determined by hierarchical clustering analysis. The experiments were accomplished twice for each cell sample, on different days, and the mean value was used for analyses. As for each EEC subtype, the mean values of three clones of each EEC subtype were used for analyses.
