Figure 4From: Gene expression modifications in Wharton’s Jelly mesenchymal stem cells promoted by prolonged in vitro culturingIPA functional analysis and first top network associated with the Cluster 2. (A) Bar chart shows key function associated with genes found to be down-regulated (cluster 2) at the 12th passage of WJ-MSCs as compared to cells at the 4th passage. (B) Network cluster 2: in gray are represented the down-regulated genes at the 12th passage of WJ-MSCs in vitro expanded, as compared to the same cells at the 4th passage. Transcripts not modulated along with the different passages are represented in white. Arrows indicate that a molecule acts on another molecule, while lines indicate a bind between two molecules.Back to article page
