Figure 4.

Phenotype trees constructed for (a) non-neoplastic S1 cells, (b) malignant T4-2 cells, and (c) both S1 and T4-2 cells cultured for a different number of days. The certainty of hierarchically grouping the cells of the predefined phenotypes (indicated by the leaf nodes in the highest level of the tree) into statistically more significant groups of the phenotypes is indicated by the confidence values at each level of the tree.
