Hierarchical clustering of the array.

<p>The experimental conditions were submitted to hierarchical clustering and the corresponding heat map and cluster tree are shown. The clustering analysis determines a classification in two big clusters including the acute (C1) and delayed transplant (C2). In these two clusters the MSC and the OEC induced profile at 2 days (C1.1 and C2.1) and at 7 days (C1.2 and C2.2) after acute or delayed treatment were grouped.
