Abstract excerpt
SL/Kh mice spontaneously develop pre-B lymphomas with surface phenotypes of B220+, BP-1+, Thy-1-, and surface immunoglobulin negative. The immunoglobulin heavy chain of lymphoma is clonally rearranged but the light chain gene remains in germline configuration. Studying prelymphoma stage SL/Kh bone marrow (BM), we found unusual multiclonal expansion of BP-1+ pre-B cells [34.8 +/- 5.8% (mean +/- SD)] by 4 weeks of...
