Figure 1. Gene expression profiling of O-ASC as compared to BM-MSC and SC-ASC.

Unsupervised clustering was performed to generate a dendrogram using center correlation and average linkage (A) (O-ASC1, O-ASC4, O-ASC5, BM-MSC: n = 2; SC-ASC: n = 4). IPA analysis revealed pathways with significantly different expression between O-ASC1 and O-ASC4 (B). Functions are listed from most significant (higher bars) to least significant (lower bars), and the perpendicular yellow line denotes the threshold for significance (P=0.05).
