Figure 3From: 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 1. (A) Bar chart shows key function associated with genes found to be up-regulated (cluster 1) in WJ-MSCs after 12 passages of their in vitro expansion, as compared to WJ-MSCs at the 4th passage. (B) Network cluster 1: in grey are represented the genes up-regulated in WJ-MSCs after 12 passages of their in vitro expansion, as compared to WJ-MSCs 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
