Functional classification of constitutively expressed or silent genes during myelopoiesis. Functional classification was performed using the functional annotation chart of DAVID 2006 and significantly over-represented Gene Ontology Biological Process categories (p-value < 0.01) were identified. Groups of functional categories were defined using a custom Gene Ontology SLIM and R script [69]. Complete lists of over-represented functional classes are reported in Additional file 2 and 3.
