Subtypes associated to developmental stages in T-LBL and T-ALL. (A) Unsupervised clustering of T-LBL and T-ALL based on genes associated with the T-cell developmental genes, showing clustering in the major T-ALL subtypes for most of the T-LBL samples. Range of 0 to 10 showing the log₂ transcript per millions of normalized expression values. (B) Distribution of subtypes associated with T-cell developmental stages in T-LBL and T-ALL shows great similarities, suggesting similar stages of arrest in T-LBL and T-ALL.
