Unsupervised analyses of the childhood acute leukemias. (A) HCA using Pearson correlation and average linkage on the 4,131 reporters [95% presence and a variation filter (standard deviation of 0.6)]. The majority of the leukemias segregate according to lineage and genetic rearrangement. To the right, the same gene order applied on the normal hematopoietic cells. (B) Enhanced dendogram of the leukemias and the normal hematopoietic subpopulations with the gene order maintained as in A. Samples are colored as in A. For an enlargement of this figure, see Fig. 5, in which the genetic status of the leukemias are indicated in detail.
