Abundance of selected transcripts in leukocytes from donors receiving G-CSF. This dataset (http://www.ncbi.nlm.nih.gov/sites/GDSbrowser?acc=GDS2959) was selected among studies currently available in NCBI’s Gene Expression Omnibus (GEO; http://www.ncbi.nlm.nih.gov/sites/GDSbrowser). In curated datasets, the ‘Data Analysis Tools’ button allows the user to gain access to gene expression levels by directly providing the gene name or symbol. Within non-curated datasets, the GEO2R tool allows the user to select a gene platform and to compare two or more groups of samples in order to identify genes that are differentially expressed across experimental conditions. This study analyzed the genome-wide patterns of gene expression with DNA microarrays (Affymetrix Human Genome U133 Plus 2.0 Array) in five healthy donors given G-CSF [25]. The expression levels of antigens relevant for granulocyte function are shown. Data were compared with the Mann–Whitney U test. A p value <0.05 was considered to denote statistical significance
