Abstract

Markers of acute myeloid leukemia stem cells (AMLSC) are identified. The markers are differentially expressed in comparison with normal counterpart cells, and are useful as diagnostic and therapeutic targets.

Claims (14)

1. A method of targeting or depleting acute myeloid leukemia cancer stem cells (AMLSC), the method comprising:

contacting blood cells of a human suffering from acute myeloid leukemia with an antibody that specifically binds CD99 in order to target or deplete AMLSC.

2. The method of claim 1 , wherein the antibody is a bispecific antibody that binds CD99 and a marker set forth in Table 1.

3. The method of claim 1 , wherein the antibody is conjugated to a cytotoxic agent.

4. The method of claim 3 , wherein said cytotoxic agent is selected from the group consisting of a radioactive isotope, a chemotherapeutic agent and a toxin.

5. The method of claim 1 , wherein the contacting depletes the blood cells of AMLSC.

6. The method of claim 1 , wherein the contacting is in vivo.

7. A method of targeting or depleting acute myeloid leukemia cancer stem cells (AMLSC), the method comprising:

contacting blood cells of a human suffering from acute myeloid leukemia with an antibody that specifically binds TIM3 in order to target or deplete AMLSC.

8. The method of claim 7 , wherein the antibody is a bispecific antibody that binds TIM3 and a marker set forth in Table 1.

9. The method of claim 7 , wherein the antibody is conjugated to a cytotoxic agent.

10. The method of claim 9 , wherein the cytotoxic agent is selected from the group consisting of a radioactive isotope, a chemotherapeutic agent and a toxin.

11. The method of claim 7 , wherein the contacting depletes the blood cells of AMLSC.

12. The method of claim 7 , wherein the contacting is in vivo.
