Verification of origin identity. Dendrograms based on gene expression signatures showing unsupervised hierarchical clustering of cell line HD-MAR (red box), cell line HD-MY-Z (red box), classical Hodgkin lymphoma cell lines (blue boxes), T-cell leukemia/lymphoma cell lines (golden box) and myelomonocytic leukemia cell lines (green box). (A) Note: cell line HD-MAR which was originally published as being derived from a patient with Hodgkin lymphoma¹⁰ does not cluster with eight bona fide classical Hodgkin lymphoma cell lines, but clusters with the T-cell leukemia-lymphoma cell lines. (B) Note: cell line HD-MY-Z which had been described originally as Hodgkin lymphoma-derived¹¹ clusters with the myelomonocytic cell lines and not with the classical Hodgkin lymphoma cell lines. Modified from reference.^9.
