Figure 2From: Gene Expression Profiles in Alveolar Macrophages Induced by Lipopolysaccharide in HumansUnsupervised hierarchical clustering of gene expression profiles in alveolar macrophages obtained from seven individuals (S) subject to saline instillation into a lung subsegment and LPS into the contralateral lung. The hierarchical clustering analysis clearly distinguished the expression patterns between saline (purple dendrogram) and LPS (blue dendrogram) samples. Each row represents a gene; each column shows the expression of 4,807 probe sets (2,932 unique genes) expressed by each sample. Red indicates genes that are expressed at higher levels, and green indicates genes that are expressed at lower levels.Back to article page
