Figure 1From: Influence of vascular endothelial growth factor stimulation and serum deprivation on gene activation patterns of human adipose tissue-derived stromal cellsDirected acyclic graphs. Directed acyclic graphs (DAG) showed a strong representation of regulated genes employing proteins in the extracellular space particularly within the categories extracellular matrix and protein binding comprising integrin binding and growth factor activity (section of gene ontology analysis top 10 significantly regulated genes; serum deprivation compared to 10% serum in culture medium).Back to article page
