Summary for Patent: 8,748,113
Title:Methods for detecting and monitoring circulating cancer stem cells
Abstract: Provided herein are compositions, methods, and kits useful for detecting whether a subject has or is likely to develop a cancer and for monitoring, staging and examining a cancer patient. Also provide herein are methods for screening compounds.
Inventor(s): Matsui; William (Baltimore, MD), Jones; Richard J. (Baltimore, MD), Huff; Carol A. (Ellicott City, MD)
Assignee: The Johns Hopkins University (Baltimore, MD)
Application Number:12/743,180
Patent Claims:1. A method for monitoring the effectiveness of a cancer treatment in a patient, wherein the cancer treatment is for leukemia, comprising the steps of: (a) obtaining a blood sample from the patient; (b) isolating a predetermined population of cells from the blood sample, wherein the isolated cells are CD34.sup.+ and CD38.sup.-, using at least one of flow cytometry, fluorescence activated cell sorting, antibody-dependent depletion, antibody-dependent solid phase capture, panning, affinity column separation, and magnetic selection; (c) determining whether the isolated cells are ALDH.sup.+; and (d) comparing the number of ALDH.sup.+ cells with the number of ALDH.sup.+ cells determined at an earlier time in the cancer treatment.

2. A method for monitoring the effectiveness of a cancer treatment in a patient, wherein the cancer treatment is for multiple myeloma, comprising the steps of: (a) obtaining a blood sample from the patient; (b) isolating a predetermined population of cells from the blood sample, wherein the isolated cells are CD138.sup.-, CD27.sup.+, CD19.sup.+ and CD20.sup.+, using at least one of flow cytometry, fluorescence activated cell sorting, antibody-dependent depletion, antibody-dependent solid phase capture, panning, affinity column separation, and magnetic selection; (c) determining whether the isolated cells are ALDH.sup.+; and (d) comparing the number of ALDH.sup.+ cells with the number of ALDH.sup.+ cells determined at an earlier time in the cancer treatment.

3. The method of claim 2, wherein the isolated cells are also CD52.sup.+.

4. The method of claim 2, wherein the isolated cells are also CD34.sup.-.

5. A method for monitoring the effectiveness of a cancer treatment in a patient, wherein the cancer treatment is for Non-Hodgkin's lymphoma, comprising the steps of: (a) obtaining a blood sample from the patient; (b) isolating a predetermined population of cells from the blood sample, wherein the isolated cells are CD19.sup.+ and CD20.sup.+, using at least one of flow cytometry, fluorescence activated cell sorting, antibody-dependent depletion, antibody-dependent solid phase capture, panning, affinity column separation, and magnetic selection; (c) determining whether the isolated cells are ALDH; and (d) comparing the number of ALDH.sup.+ cells with the number of ALDH.sup.+ cells determined at an earlier time in the cancer treatment.

6. The method of any one of claims 1-5, wherein the cancer treatment is a stem-cell targeted therapy, induction of terminal differentiation, inhibition of telomerase, inhibition of developmental signaling pathways, inhibition of intracellular signal transduction pathways, induction of active immunity to cellular antigens, induction of passive immunity to cellular antigens, a hedgehog inhibitor, a cytotoxic agent, an antiproliferative agent, a targeting agent, a biologic agent, rituximab, alemtuzumab, or an HDAC inhibitor.

7. The method of claim 6, wherein the targeting agent is a kinase inhibitor or a cell cycle regulator.

8. The method of claim 6, wherein the biologic agent is a cytokine, vaccine, viral agent, or immunostimulant.
