Values refer to the Affymetrix® GeneChip® Command Console® (AGCC). Macrophages alone (Mφ) or cultured in Transwell (Tw) for 48 h with mesoangioblast stem cells (Mφ Tw MAB) were screened for gene array analysis. Signals for transcripts with a present call are shown in gradient-coloured cells from blue (low abundance) to dark red (very highly abundant transcript). Expression of macrophages genes that were modulated in a statistically significant manner after culture with mesoangioblasts are reported. Data are from three independent experiments
