Transcriptional characterization of human bone marrow monocytes. (A) Unbiased cluster analysis of gene expression of ABM and FBM classical monocytes. (B) Scatterplot of pairwise global gene expression comparing ABM and FBM classical monocytes (log₂ signal intensity). Genes that were differentially expressed between groups are indicated in red and blue. Genes of interest in green are also significantly differentially expressed (FDR ≤ 0.05, fold change ≥2). (C) log₂ fold change of genes in green (fetal vs adult).
