The genes of each cluster were uploaded individually to online databases (DAVID and KEGG) and analyzed for their link to different biological parameters like gene ontology, cellular compartmentalization, molecular function, signaling pathway and site of expression. The parameters were selected on the basis of the enrichment score and relevance for adipogenesis. The numbers given in brackets are the numbers of genes associated to the corresponding GO term and signaling pathways.
