Abstract/OtherAbstract:
Abstract Understanding the biology of Waldenström Macroglobulinemia is hindered by a lack of preclinical models. We report a novel cell line, RPCI-WM1, from a patient treated for WM. The cell line secreted human IgM (hIgM) with k-light chain restriction identical to the primary tumor. The cell line has a modal chromosomal number of 46 and harbors chromosomal changes such as deletion of 6q21, monoallelic deletion of 9p21 (CDKN2A), 13q14 (RB1) and 18q21 (BCL-2) with a consistent amplification of 14q32 (IgH) identical to its founding tumor sample. Clonal relationship was confirmed by identical CDR3 length, and single nucleotide polymorphisms as well as a matching IgH sequence of the cell line and founding tumor. Both also harbor a heterozygous, non-synonymous mutation at amino acid 265 in MYD88 gene (L265P). The cell line expresses most of the cell surface markers present on the parent cells. Over all, RPCI-WM1 represents a valuable model to study WM.
