| Abstract: | The development of an in vivo model for the study of CML would be of significant importance in studying its biological behavior and developing novel therapeutic strategies. We examined the ability of human leukemic cells derived from patients in either chronic (CP), accelerated (AP) or blast phase (BP) CML to grow and disseminate in CB17-SCID mice by subcutaneous (s.c.) inoculation without conditioning treatment or administration of cytokines. Additionally, samples derived from patients with CP-CML were injected s.c. into CB17-SCID mice treated with anti-Asialo GM1 (an anti-NK cell antibody) and NOD-SCID mice (absent NK cell activity) to study the potential role of NK cell-mediated anti-leukemic activity in preventing the propagation of CP-CML cells. We observed a significant differential growth pattern of CML cells in the mice such that BP-CML grew rapidly as s.c. tumors and disseminated, while AP-CML or CP-CML cells grew temporarily as small nodules that spontaneously regressed and did not disseminate. This differential growth pattern suggests possible important biological differences. Furthermore, no significant difference in s.c. growth or dissemination of CP-CML samples derived from newly diagnosed patients in untreated CB17-SCID mice and CB-17 SCID mice treated with Anti-Asialo GM1 and NOD-SCID mice occurred, suggesting that factors other than NK cell anti-leukemic activity may be important. |
