A Comparison of Differences in the Gene Expression Profiles of Phorbol 12-myristate 13-acetate Differentiated THP-1 Cells and Human Monocyte-derived Macrophage

In order to characterize the monocytic cell line THP-1 and its mature, macrophage-like form treated with phorbol 12-myristate 13-acetate (PMA), we have conducted an oligonucleotide microarray assay and compared the results with those from an assay of human monocytes and macrophages. We found that early THP-1 cells have a pattern of gene expression distinct from monocytes, and when treated with PMA, certain genes which are induced in macrophages,...
