Molecular Profiling Predicts the Existence of Two Functionally Distinct Classes of Ovarian Cancer Stroma

Figure 1

Hierarchical clustering of OSE, Cepi, NS, and CS expression profiles. The heat map was generated by 𝑧-score normalization of log₂ expression values from Affymetrix HG U133 Plus 2.0. The results show that the OSE, Cepi, NS, and CS samples cluster into separate groups. The CS samples clustered into two distinct subgroups (CS₁ and CS₂).
