(in Diehl et al). Two-dimensional cluster analysis of the 5 classical Hodgkin’s lymphoma cell lines (L1236, L428 and KM-H2 [B-cell type]; L540 and HDLM-2 [T-cell type]) using 29 genes that are statistically significantly different expressed (Student t-test, P-value cutoff .05 including correction by Benjamini and Hochberg False Discovery Rate) between B-cell and T-cell type classical Hodgkin lymphoma cell lines.
