Column labels are as follows: N1 is the number of genes for a Gene Ontology (GO) category in the unselected marker set; N2 and P2 are the number of genes and P value for the smaller marker set; N3 and P3 are the number of genes and P value for the markers highly expressed in differentiated stem cells; GO is the description of the GO term; and GOID is the GO identifier. P values are computed using the 'All' set of markers as background. GO terms displayed if they represent more than ten genes have at least one associated P value below 0.01 and do not overlap more than 80% with another displayed term.
