Based on the presence of T cell receptor-beta ( TcR-beta ) gene rearrangements in L428 and HDLM-1 cells , the expression of CD2 in HDLM-1 cells , and the presence of immunoglobulin heavy-chain ( IgH ) gene rearrangement in KM-H2 cells , some researchers have concluded that these long-term cell lines derived from patients with Hodgkin's disease are lymphoid in nature.
