The method of claim 1, wherein the mammal is a human. 6. The method of claim 2, wherein the mammal is a human. 7. The method of claim 3, wherein the mammal is a human. 8. The method of claim 4, wherein the mammal is a human. 9. The method of claim 1, wherein the hematologic malignancy is selected from the group consisting of acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelomonocytic leukemia, myelofibrosis and myelodysplastic syndrome. 10. The method of claim 2, wherein the hematologic malignancy is selected from the group consisting of acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelomonocytic leukemia, myelofibrosis and myelodysplastic syndrome. 11. The method of claim 3, wherein the hematologic malignancy is selected from the group consisting of acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelomonocytic leukemia, myelofibrosis and myelodysplastic syndrome. 12. The method of claim 4, wherein the hematologic malignancy is selected from the group consisting of acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelomonocytic leukemia, myelofibrosis and myelodysplastic syndrome. 13.
