Similarities and differences in the transcriptome of human atherosclerotic and non-atherosclerotic macrophages

Macrophages were isolated from N=4 tissues, being atherosclerotic plaques from carotid artery (CA), and from three none-atherosclerotic tissues, being lung (LU), spleen (SP), and liver (LI). This was done within four individual patients, defined as 275, 282, 288 and 289.Each of the N=16 biological samples was hybridized in duplicate against a common reference RNA, resulting in a total of N=16 microarray hybridizations.
