| 20080220453 | Identification and isolation of squamous carcinoma stem cells - Squamous carcinoma stem cells (SCSC) are identified. The cells can be prospectively isolated or identified from primary tumor samples, and are shown to possess the unique properties of cancer stem cells in functional assays for cancer stem cell self-renewal and differentiation, and to form unique histological microdomains useful in cancer diagnosis. | 09-11-2008 |
| 20090191202 | Methods for manipulating phagocytosis mediated by CD47 - Methods are provided to manipulate phagocytosis of cells, including hematopoietic cells, e.g. circulating hematopoietic cells, bone marrow cells, etc.; and solid tumor cells. In some embodiments of the invention the circulating cells are hematopoietic stem cells, or hematopoietic progenitor cells, particularly in a transplantation context, where protection from phagocytosis is desirable. In other embodiments the circulating cells are leukemia cells, particularly acute myeloid leukemia (AML), where increased phagocytosis is desirable. | 07-30-2009 |
| 20100226927 | SELECTIVE IMMUNODEPLETION OF ENDOGENOUS STEM CELL NICHE FOR ENGRAFTMENT - The present invention provides a clinically applicable method of stem cell transplantation that facilitates engraftment and reconstitutes immunocompetence of the recipient without requiring radiotherapy or chemotherapy, and without development of GVHD or graft rejection. Aspects of the present invention are based on the discovery that the depletion of the endogenous stem cell niche facilitates efficient engraftment of stem cells into that niche. In particular, the present invention combines the use of selective ablation of endogenous stem cells, in combination with the administration to the recipient of exogenous stem cells, resulting in efficient, long-term engraftment and tolerance. | 09-09-2010 |
| 20100267079 | Identification and isolation of transitional cell carcinoma stem cells - Transitional cell carcinoma stem cells (TCCSC) are identified. The cells can be prospectively isolated or identified from primary tumor samples, and are shown to possess the unique properties of cancer stem cells in functional assays for cancer stem cell self-renewal and differentiation, and in cancer diagnosis. | 10-21-2010 |
| 20100287631 | WNT PATHWAY MUTATIONS IN CANCER STEM CELLS - Cancer specific splicing events in the Wnt/β-catenin signaling pathway are associated with progression of myelogenous leukemia. Misspliced genes of interest include GSK3β. In some embodiments of the invention, polynucleotides are provided that correspond to misspliced GSK3β transcripts associated with cancer. Such transcripts are characterized by a deletion of exon (8), and particularly in exon (8) and (9). Detection of such transcripts in cells is indicative of the presence of leukemia, and particularly of the presence of leukemia stem cells. In other embodiments, polypeptides are provided that are encoded by misspliced GSK3β transcripts associated with cancer. Such polypeptides are useful as diagnostic markers for cancer, and as a target for screening of therapeutic agents. Animal models comprising a human LSC having a misspliced GSK3b transcript provide a useful model for leukemia, for drug/gene screening in the prevention and treatment of leukemia in humans, etc. | 11-11-2010 |
| 20110014119 | Methods for Manipulating Phagocytosis Mediated by CD47 - Methods are provided to manipulate phagocytosis of cancer cells, including e.g. leukemias, solid tumors including carcinomas, etc. | 01-20-2011 |
| 20110015090 | Markers of Acute Myeloid Leukemia Stem Cells - 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. | 01-20-2011 |
| 20110076683 | Identification, Isolation and Elimination of Cancer Stem Cells - Isolated populations of leukemic stem cells are provided. The cells are useful for experimental evaluation, and as a source of lineage and cell specific products, and as targets for the discovery of factors or molecules that can affect them. Detection of leukemic stem cells is useful in predicting disease progression, relapse, and development of drug resistance. Proliferation of LSC may be inhibited through interfering with activation of the β-catenin pathway. Methods are provided for the clinical staging of pre-leukemia and leukemias by differential analysis of hematologic samples for the distribution of one or more hematopoietic stem or progenitor cell subsets. | 03-31-2011 |
| 20110124032 | Methods and Compositions for Treating Carcinoma Stem Cells - Cancer stem cells (CSCs) have been prospectively isolated or identified from primary tumor samples, and shown to possess the unique properties of self-renewal and differentiation, and can form unique histological microdomains useful in cancer diagnosis. Such cancer stem cells are shown herein to have the phenotype of containing decreased levels of reactive oxygen species (ROS) relative to non-tumorigenic (non-stem cell) cancer cells, as well as expression of other protective pathways. The CSCs are further shown to be more resistant to ionizing radiation (IR) and certain chemotherapies and to express high levels of ROS genes. | 05-26-2011 |
